Place: Satellite Launch Centre,
Sriharikota
Just a month into office, Prime
Minister Narendra Modi had travelled to the ISRO (Indian Space Research
Organisation) facility to witness the launch of the PSLV-C23
satellite. In his speech after the successful launch, Modi praised the ISRO
scientists for their stellar work and then stunned them into momentary silence
by posing a challenge. “Today,
I ask our Space community, to take up the challenge, of developing a SAARC
Satellite - that we can dedicate to our neighbourhood, as a gift from India. A
satellite, that provides a full range of applications and services, to all our
neighbours. I also ask you, to enlarge the footprint of our satellite-based
navigation system, to cover all of South Asia.”
Initially, the assembled scientists did not know what to say. “We had
never done such a thing,” remembers an old ISRO hand. Modi reinforced this idea five months later, speaking in Kathmandu at
the SAARC Summit on November 26. He said, "India's gift of a satellite for
the SAARC region will benefit us all in areas like education, telemedicine,
disaster response, resource management, weather forecasting and communication.”
In less than three years after the Prime Minister
challenged the ISRO scientists, they came up with the answer. On 5 May 2017,
the SAARC Satellite’ was launched from Sriharikota, opening a new chapter in
space diplomacy.
The 2,230 kgGSAT-9 is a Geostationary Communication
Satellite. Communication services from it will be shared with five neighbours
(Bhutan, Nepal, Sri Lanka, Bangladesh and Maldives). It will help to meet the
growing telecommunications and broadcasting needs of the region. All
participating nations will have access to at least one transponder using which
they can telecast their own programming. The countries will develop their own
ground-level infrastructure. The satellite is expected to provide communication
channels between countries for better disaster management. Afghanistan is also
expected to join the group soon. As a scientist in ISRO says, “For smaller
countries, this is a dream come true. To lease a transponder, a lot of money
has to be spent. But here India has gifted them a permanent asset.” Apart from
the obvious use (telecommunication, broadcasting), leaders of these six
countries can have secure dedicated one-on-one communication through the VSAT
facility that the satellite provides, explained ISRO officials. The leaders can
also have a video conference between themselves if they so wished, thanks to
the South Asia satellite.
In a way, by dedicating a separate
satellite for the neighbourhood, Modi has taken his favourite theme of SabkaSaath, SabkaVikas, beyond India’s
own physical boundaries. An early example of helping neighbours through
satellites came in Nepal. In August 2014, a massive landslide blocked Sun Koshi river in Northern Nepal indicating the
possible formation of a lake. This created flood threat for several villages
downstream in Bihar.
ISRO immediately
swung into action, acquired the images and in consultation with India’s
National Disaster Relief Agency (NDMA) could get to exact location of
landslide, compute the extent of debris due to landslide and could come up with
a solution for controlled release of blocked water slowly, averting possible flash
floods in Bihar. This operation was made possible because ISRO now coordinates
closely with Inter-Ministerial
Group for Emergency management at the Centre. IMEG helped coordinate the relief
operation in Nepal and later in September 2014 in Srinagar too.
But that’s not all.
As ISRO Chairman K. Kiran Kumar sees it,“While
ISRO has always been a pace-setter in space application Prime Minister Modi and
NSA Ajit Doval have spurred us into taking our technology a step higher.” He
cites the example of ‘Island mapping’ programme launched in 2015.
Apparently in one of the meetings in the PMO
sometime in June 2015 Modi asked the number of islands India possesses. As
officials from MHA scrambled to get the exact figures from Survey of India,
some officials in the PMO itself tried to add up the number by getting the
figures from state governments and from the census records. But the figures
varied widely. It was clear that the records were old and not updated in years.
That’s when NSA Doval turned to ISRO. He asked
ISRO chairman Kiran Kumar if the space agency could help in determining the
exact number of islands. Kiran Kumar was quick to say yes. Remembers PG
Diwakar, currently Scientific Secretary to the ISRO Chairman: “I was then
in-charge of Remote Sensing Applications at NRSC. The Chairman asked me to
devise a quick method to map the islands around India’s vast coastline.” He got
down to work immediately with a hand-picked team. “We were asked to not just
determine the numbers but also look at their exact status, distribution and
area (of the islands). We were particularly told to recheck the status of the islands
that were on the Survey of India list from the British days. The fear was that
some of them would have gone underwater while some others would have sprung
up,” Diwakar recalls.
The unspoken apprehension behind the exercise
was the possibility of some remote, uninhibited island in Andaman-Nicobar
territory or around Lakshadweep or even in the Sundarbans being illegally occupied!!.
Security agencies were aware of how arms smugglers had used a remote island in
Andaman in 1998 to land a large consignment of arms meant for Burmese rebels
and tried to transport it across the Bay of Bengal to be delivered in Myanmar.
The agencies had foiled the consignment in well-coordinated plan under
Operation Leech in February 1998. Nearly twenty years later, the likelihood of
an uninhibited island being occupied by forces aligned to India’s adversaries
has increased manifold. The exercise thus had strategic implications too.
Once the number was determined, the ISRO team
developed an Island Information System that has 34 attributes (give details). The
Prime Minister was briefed about the system in October 2016. Since then, the NITI
Aayog, state governments and other ministries have started to draw up
development plans for 10 selected islands, five each in Andaman and Lakshadweep.
At the same time, ISRO satellites are
keeping a continuous watch on these island territories. A software that updates
any noticeable changes on these islands has since been developed too. So as
Diwakar and his team drew up the latest data base on islands, they came up with
new discoveries. “Says Diwakar: “This
work became very popular because we built this information system within a few months
and were able to demonstrate this to MHAand other Ministries that were involved
in the exercise. The Home Ministry had then called in many other ministries who
are relevant in this exercise and also needed this data. For example, the
Indian Navy and Coast Guard, the Census people, Environment & Forests and
the Survey of India officers, all came on board. What we did is we brought on a
common platform, an information system which can be used by multiple ministries.” For example, an IG of Police from Gujarat
told ISRO scientists that his force is now able to monitor vulnerable islands
close to the maritime boundary with Pakistan much more closely and take counter
measures accordingly.
The Island Information System apart, ISRO has successfully
launched CARTOSAT 2 Series of satellites that can provide sub-meter images
(spatial resolution of 65 cm) for monitoring purposes. ISRO is also building on
capabilities to acquire images from as far as 36,000 km up in the space and yet
give a resolution of about 55 m, at frequent intervals, empowering Indian
security agencies like the National Technical Research Organisation (NTRO) and
other intelligence arms to monitor real time activities of India’s adversaries.
Such a capability would also help in effective monitoring of major national
disasters in the country.
The Special Projects Division dealing with all
strategic requirements of the armed forces and intelligence agencies has been
reinvigorated. A senior scientist in charge of the Division works in close
coordination with the Deputy National Security Adviser to meet all requirements
in quickest time possible. So, for instance, while new and powerful ISRO
satellites are continuously monitoring India’s immediate and extended
neighbourhood as a matter of routine, a specific request like the one to hover
over areas in Pakistan-Occupied Kashmir (PoK) in the wake of the Uri attack in
September 2016 was handled by the Special Projects Division. For a week in the
run up to the surgical strikes in late September that year, ISRO kept a close
and specific watch on terrorist camps and movement of Pakistani army troops.
When Indian Special Forces crossed the Line of Control (LoC) and struck several
locations inside PoK, real time surveillance was mounted by ISRO both to
capture the assault and to monitor any threatening movement against the Indian
Special Forces teams.
In June and July 2017, at the height of a tense
standoff between India and China in Chumbi Valley just north of the Siliguri
corridor, connecting rest of India with the north eastern states, ISRO was
tasked with monitoring Chinese military activity in Tibet to determine if there
was any unusual movement of troops, tanks or aircraft. Besides, ISRO now
provides real time support to Indian Navy and Coast Guard to keep a close watch
on the long coastline as well as the vast Exclusive Economic Zone (EEZ) that
India has. Movement of Chinese survey ships, submarines and warships in the
Indian Ocean and Bay of Bengal besides the Pakistani Navy’s forays into Arabian
Sea, in conjunction with the Navy, is now one of the important tasks of ISRO
following the new coordination mechanism established in 2015.
ISRO has in fact been continuously
launching a series of satellites, mainly for cartography purpose. Called the Cartosat
series, these satellites are mainly used for cartographic mapping the earth. So
they are useful for dual purposes—military as well as civil. Through the
Cartosat 2 series of satellites programme for instance, ISRO is helping derive1x4000
scale maps for better urban planning. As Kiran Kumar says, “the beauty of this technology
is that it is continuously available. One can take an image today, one can take
an image again, 15 days later, compare and monitor the progress of a project, a
building or whatever else. With two-time data, say between 2007 and 2017, we
can calculate the difference in height of a given building through stereo imaging
and three-dimensional mapping and calculations to establish building heights,
Mining related works or even new constructions.”
K Kasturirangan, former chairman of ISRO,
says "The space agency has a formidable suit of technologies and all are
suitably deployed with each user agency utilising the assets to their best
advantage."
So while high resolution imaging satellite can help in urban planning it can
also monitor terrorist camps across the border. Kasturirangan says a satellite
image does not distinguish between friend and foe that interpretation rests
with the users. Kiran Kumar says, "The Indian space agency will not
be found lacking in helping secure India's national interests now and in
future."
Speaking about the capabilities of this ultra-sharp satellite, Kumar said
"The Cartosat 2 series has a unique capability of capturing a 1-minute
video, which despite its enormous speed of 37 km a second, is able to focus at
a single point for a minute."
In addition, there were three other earth
imaging satellites Cartosat-1, Cartosat-2 and Resourcesat-2 that provide top
class imagery during day time. Going further, ISRO seeks to develop satellites
that have a resolution of 25 cm in the very near future.
Former ISRO chairman G Madhavan Nair says even China does not have such high
resolution satellites, the best China has is about 5-m resolution.
Nair says "India invested heavily in
space imaging technology and is now reaping the benefits." Nair
says right now India relies heavily on using Thuraya handsets for satellite
telephony but he hopes very soon the Defence Research and Development
Organisation (DRDO) will be able to deliver Indian handsets that are compatible
with the country's GSAT-6 satellite.
In fact Nair insists that in the upcoming GSAT 6-A, satellite telephony should
be made the bigger component.
While understandably much of the
resources are focused on land since India has hostile neighbours both on its
western and eastern fronts. ISRO has not forgotten the deep blue oceans that
surround India and they need to be protected as well. On a specific demand by
the Indian Navy, the Indian space scientists have already deployed a satellite
the Navy calls 'Rukmini'. This is a dedicated communications satellite which
helps the Indian Navy talk to its ships when they are beyond the visual range,
in a secure fashion.
As
a senior security manager summed it up: “Now ISRO has got strategically aligned
to India’s security requirements, thanks to the Eye-in-the-Sky. Earlier, it was
largely technologically focused.”
Another feather in ISRO’s cap is the Indian
National Regional Navigational System, meant for creating India’s own GPS
facility. Having put up a constellation of seven satellites which covers India and the
neighbourhood—up to 1500 km to the east and west of India’s shores—ISRO has
created a powerful system which is used for several important tasks including
creating India’s own GPS system. This constellation
of seven satellites was named as "NavIC" (Navigation Indian
Constellation) by Prime Minister Modi and dedicated to the Nation on the
occasion of successful launch of IRNSS-1G, the seventh and last satellite of
NavIC. Navic in Sanskrit is incidentally, a sailor.
All the satellites will be visible
at all times in the Indian region. While the first of the series of satellites
was launched in July 2013, the rest six were put into space between 2014 and
2016.ISRO spent Rs. 1,420 crores on building and setting up the seven NavIC
satellites in the orbit. Regarded as a precise system, comparable to US's GPS,
NavIC is capable of providing position accuracy of about 10 metres. India has
thus become one among a handful of countries, to have its own GPS. IRNSS
Or NavIC will provide two types of services, namely, Standard Positioning
Service (SPS) which is provided to all the users and Restricted Service (RS),
which is an encrypted service provided only to the authorised users. The indigenous system is
already up and providing services that is being tested and used a few
applications already. Says an ISRO
official: “From 2018, we need not depend on US GPS at all.”It’s a major
strategic advantage.
Based on the Indian GPS system, ISRO has tied up
with Indian companies—under Make in India projects--for manufacture of a chip
set. Once the chips are produced, they can be used for variety of purposes,
from defence to simple road navigation in the civilian sector. Several trials
have taken place of late. NavIChas started supporting the fisherman in coastal
areas. Says Kiran Kumar, “the first application (of NavIC) which we have
devised is given through a mobile App, a basic mobile. Once installed and
linked to the NavIC Device, a fisherman in say Gujarat or in Tamil Nadu will
get important services, like 1. Potential Fishing Zones (PFZ) information for
him to navigate to that point for fishing, 2. Weather alert, like thunders
storms, 3An automatic alert if his boat approaches international maritime
boundary. Otherwise, on high seas, it is difficult to make out where the Indian
area ends and other country’s begins.” Given the frequency of arrests of Indian
fishermen in Pakistani or Sri Lankan waters, NavIC must come as a big relief to
the fishermen community.
ISRO has already developed necessary Apps on
Mobile that will allow fishermen to download potential fishing zones in the
area before they launch the boat into the sea. Explains Diwakar: “Here, what we
do is we use the sea surface temperature and chlorophyll information, which
comes from the satellite data, Oceansat-2 is used here, both these are
integrated to determine an area which would have a school of fish, that around
this lat-long, the fishermen need not waste time in searching for fish as he
can follow the PFZ maps and reach the right place for assured fish-catch.” This
is in fact the first application based on NavIC, which is already in
field-trial phase.
Once tested and tried, the chipset may even
become integral part of every mobile handset in India to provide accurate GPS
to everyone, ISRO scientists now say. There will be multiple applications that
NavIC can be used for.
However, ISRO’s mandate goes much beyond
just helping India’s strategic sector. Chairman Kiran Kumar says the scope and
work of ISRO has expanded manifold since the Modi government has taken charge
in 2014. In fact, the Chairman of ISRO says under this government, the number
of ministries using ISRO data has gone up manifold. “From about 10-12
ministries in the past, we now have 58 ministries, including the tribal welfare
ministry (which one wouldn’t have thought would have any use of our data) have
a dedicated link to our data. That’s a huge difference.”
For example the Smart Cities & AMRUT projects
that the government has launched. ISRO provides 65 cm data, 1x4000 scale maps, to
urban planners for consistent and continuous planning and monitoring. ISRO’s
technology now gives a three-dimension imagery allowing urban planners to
record progress of a construction site. Project managers can now map the
progress of various construction activities by comparing earlier images with
the latest ones at a central place, on a dashboard. ISRO’s ability to map potential
ground water zones, provide acreage and production of major crops well before
harvest, monitor encroachments in forest in addition to mapping and monitoring
forest reserves, assess quality of land (whether it is fallow, a wasteland or
fertile), gives a handy tool to town planners. They can now plan to make
optimum utilisation of water, electricity, energy since the entire three
dimensional view of the proposed town or a city in progress is available. Once
a new city comes up, many of its basic civic functions can be controlled,
managed and utilised through a central system, thanks to ISRO’s technology.
Says Diwakar, “If I am a town planner, I would like
to optimally utilize resources in a cost effective manner, let us say, the
water, electricity and sewerage systems. I wouldn’t like to waste the precious
water. So you can completely control through ICT technologies on how you’re
going to distribute the water in a city. Through the computerised mechanism you
release the water to a particular area for a particular time, you auto shut-off
and close it since you know the amount of water the population is going to
consume. ISRO scientists say their technology gives an integrated perspective
and the ability to modify outcomes as and when required. For instance, they can
effectively do traffic management by using ICT because the control room has the
full picture and ability to monitor the amount of load on a given road and
identify choke points during different hours. Near real-time monitoring and
making real-time projections helps in better urban management. And at nights the
control room can even manage street lighting and control energy consumption of
a particular area based on traffic and use of public places. The control room
manager can switch on /switch off or even reduce the illumination for a certain
area if there’s no traffic, say after 12 midnight. In short, the Central
control room concept in a smart city can literally manage and monitor all the basic
amenities and facilities which are used by common citizens daily. Yet another
possibility of using “Internet of Things (IOT”, intermixed with space
technology helps in better management of smart cities. The capital of
Chattisgarh—Naya Raipur—that is moving towards smart city program is one of the
unique examples of marrying urban planning with space technology, ISRO
scientist point out.
AMRUT or Atal Mission for Rejuvenation
and Urban Transformation is another example where urban bodies (municipal
corporations, city councils) will be able to use geospatial technology for planning.
For example, urban planners can get the full picture at the click of a mouse
about the drainage situation, existing pipelines, allow them to check if space
exists for new pipelines to be laid etc. The authorities can also take a
comprehensive look at the green cover available in an urban setting thanks to
the ISRO eye in the sky and decide accordingly which areas to leave out for
construction, which to allot in case the land is found to be fallow or is a
wasteland with no hope of being used for agriculture purposes.
So wasn’t this being done earlier, I ask
the ISRO scientists. “Not at this level or with so much of coordination,” said
one of them in reply. Normally, it used to take four to five years for town
planners to finalise the city plans or even update them but now, working in
close coordination with Ministry of Urban Development the process is much
faster than before. The Ministry has modified the entire documentation with
respect to town planning, they have evolved new guidelines that uses space and
geospatial technology, so now the entire urban planning starts with a geospatial
base map, the base map given by the high resolution satellite pictures. The
satellite pictures combined with the existing maps gives full information on elevation,
type of land--waste land or a productive land—to enable faster planning. At the
moment, about 500 AMRUT towns and cities have been taken up and sought ISRO’s
help. Having tasted success, the authorities
now want to use the technology for all 4,041 cities in the future.
Explains Diwakar: “This is a procedure
we’ve put together. A client server system has been designed to be used by the
MoUD. All the services will be ‘e’ enabled services. All of them—water and waste management,
traffic system, electricity grids, housing numbers-- can be brought under one
roof and monitored in a dashboard. We are for example working with Naya Raipur
to make it one of the first modern smart cities in the country. The model should
be amenable to be emulated throughout the country.”
Planning smart cities apart, ISRO is
contributing in mounting surveillance on gas pipelines, geo-tagging all the
post offices in the country, helping tourism departments to come up with a
real-time information monitoring system and collecting data for municipal
corporations. The information of all 1.55 lakh post offices in the
country—including their location, status of road connectivity to each one of
them and even the services provided by them—is now available at one place, that
is Bhuvan Geoportal. Moreover the 3Dimensional imaging capability that ISRO now
has enables municipal authorities to monitor and compare data on building
heights. For example, simply looking at a residential building’s 3D image from
2010 and 2017—for instance—the civic authorities can calculate the number of
stories added to a building and accordingly come up with an estimate house tax
they can collect.
Similarly, for agriculture sector,
satellite imagery was used earlier too but over the past three years, the use
of ISRO satellites has gone up manifold. Says a scientist: “Our technology now
enables the agriculture department to estimate grain production much before the
harvest. Earlier we used monitor about eight crops, now the count has gone up
to 11 and also helping the ministry with Soil Health Card program in country in
addition to the Crop Insurance scheme to help the farming community. Moreover,
we have also included horticulture in this monitoring. The most important
change however is the use of ISRO technology to assess damage to crops in
drought hit areas or places that get excessive rains or flooding. This way the
government’s crop insurance programme gets implemented in double quick time. We
are actually able to provide almost real time data to enable the agriculture
department in assessing the need for crop insurance.”
Even the water resources ministry uses
space technology much more than before. Thanks to the new synergy, the Ministry
now gets the water spread information in all water bodies and reservoirs on a
bi-weekly basis through, says Diwakar. Every 15 days we get the picture of surface
water body in the entire country, he adds. This kind of data is automatically
processed and published on ISRO portal. Telangana and Andhra Pradesh States
have launched a major program on water resources management using our
technology and the advantage of such bi-weekly data on water from space.
ISRO’s achievements are already formidable
but with growing use of space for defence and commercial purposes, its role is
bound to increase and it must therefore strive to remain ahead of the curve by
inviting India’s private sector to forge a beneficial partnership. As Rajeswari Pillai Rajagopalan,
senior fellow and head, Nuclear & Space Policy Initiative, at the Observer
Research Foundation says, “India has a
sizeable and talented private sector that must be brought in to maximize the
capacity to manufacture as well as launch satellites. Isro might need to do a
bit of handholding in the beginning but with a little help the Indian private
sector can contribute to India’s space growth story in an effective manner.”
Increasing private sector
participation part, ISRO will need to remain focused on India’s defence and
strategic requirements in coming years and contribute much more than before in
securing India through precise application of its capabilities even as it continues
to attain new heights in commercial application of space assets.
