GSAT 10 set for launch

Posted by- Neelam Mathews
Press Release

GSAT-10 satellite, ISRO’s 101st space mission, is ready to be launched
from the Kourou launch base in French Guyana. GSAT-10, weighing 3400 kg at
the lift off, is the heaviest that ISRO has built. GSAT-10 has been
integrated with the Ariane-5 launch vehicle along with co-passenger
communication satellite ASTRA-2F awaiting the launch scheduled at 0248 hrs
on September 29, 2012 (IST). Necessary arrangements are being done for
live telecast of the launch from Kourou Launch Base through Doordarshan.

About 31 minutes after lift off, GSAT-10 would be injected in a
Geosynchronous Transfer Orbit with a perigee of 250 km and an apogee of
about 36,000 km. From there, the satellite would be moved to Geostationary
Orbit (circular 36,000 km above equator) by using the satellite propulsion
system in a three step approach. After this, the solar panels and antennas
would be deployed. In the next few weeks, the payload would be turned on
to perform a series of extensive In-orbit Tests. The satellite is expected
to be operational by November 2012. GSAT-10 satellite will be positioned
at 83 deg East orbital location along with INSAT-4A and GSAT-12. The
nominal operational life of GSAT-10 is expected to be 15 years.

GSAT-10 satellite, carrying 30 communication transponders   [12 Ku-band,
12 C-band and 6 Extended C-Band] would provide vital augmentation to
INSAT/GSAT transponder capacity. Also, it has a Navigation payload “GAGAN”
that would provide improved accuracy of GPS signals (of better than 7
meters) to be used by the Airports Authority of India for Civil Aviation
requirements. This is the second satellite in INSAT/GSAT constellation
with GAGAN payload after GSAT-8, launched in May 2011.


  1. Thanks for sharing the nice information regarding the GSAT-10 satellite. It's very helpful in airport security.

    Thanks for it.

  2. Do you have any information about the status of GSAT-10?
    It has been 5 months since its launch, still it is not operational. Is it another failed satellite from ISRO?
