The Indian Space Research Organisation (ISRO) has
lined up a slew of launches for its workhorse Polar Satellite
Launch Vehicle (PSLV). While primarily the missions are
for Indian payloads, in some cases PSLV will carry foreign
such mission will be in 2005-06 when PSLV will carry an
earth observation micro-satellite, X-SAT, owned by Nanyang
Technological University (NTU), Singapore. ISRO's commercial
arm, Antrix Corporation, has signed an agreement with
NTU and is also providing support in satellite development
one of its missions PSLV will also carry a space recovery
capsule that is currently under planning stage. According
to plans, the capsule will be put in polar sun-synchronous
orbit during 2004-05. With this, India takes the first
step towards developing reusable vehicle.
R V Perumal, associate director (projects), Vikram Sarabhai
Space Centre (VSSC), part of ISRO: "We will do some
micro-gravity experiment in the orbit, which will have
applications in natural science and pharmaceuticals by
putting relevant equipment in the capsule." The capsule
will re-enter the atmosphere and will be recovered from
the sea, as it will float. It will be a parachute landing
for the capsule."
to Dr K Kasturirangan, chairman, ISRO and secretary, Department
of Space, a series of remote sensing and cartography satellites
will be sent up during the next five years. The first
remote sensing satellite to go will be the ResourcesAT1
(IRS P6). It will carry the following payloads:
multi-spectral camera providing 23.5 m spatial resolution
in four spectral bands with a swath of 140 kms,
high-resolution multi-spectral camera with across track
steerability providing 5.8-metre spatial resolution
and 23.5 kms swath and operating in three spectral bands,
advanced wide field sensor with a spatial resolution
better than 56 metres in three spectral bands and providing
a swath of 740 kms.
will be placed in a sun-synchronous polar orbit of 800
kms. It will not only provide service continuity to IRS-1C
and IRS-1D but also enhance the service capabilities in
the areas of agriculture, disaster management, and land
and water resources with better resolution imageries.
satellites for advance cartographic applications
CARTOSAT-1 and CARTOSAT-2 are getting ready. The
first one, slated during 2003-04, will have two panchromatic
cameras with a spatial resolution of 2.5 metre and a swath
of 30 kms each. The data products will be used for cartographic
applications, cadastral mapping and updating, land use
and other GIS applications.
the other hand CARTOSAT-2 will have a single panchromatic
camera that would provide scene-specific spot imageries
for cartographic applications. The panchromatic camera
is designed to provide better than 1-metre spatial resolution
imageries with a swath of 10 kms. The satellite is planned
for launch in 2004-05.
year ISRO initiated development of a microwave remote
sensing satellite, RISAT which would observe even during
night and cloudy conditions. Apart from the NTU's some
other micro satellites will piggyback on PSLV's main payload.
One such payload is the educational micro-satellite developed
by Anna University.
HAMSAT is another micro-satellite designed to provide
satellite-based radio amateur services to Indian and international
HAM (amateur radio operators) community. According to
the Department of Space, HAMSAT will have Linear Mode
transponders one transponder to be built by Indian
amateurs and the other to be provided by AMSAT, Italy
/ the Netherlands. The satellite will weigh 40 kgs.
