GSAT-10 Placed in Intermediate Orbit

In the first critical orbit-raising manoeuvre conducted this morning (September 30, 2012), the perigee (nearest point to Earth) of GSAT-10 satellite has successfully been raised from 250 km to 16,427 km by using the satellites on-board propulsion system. Besides, the inclination of GSAT-10 with respect to the equatorial plane has also been brought down to 1.7 deg from the earlier 5.998 deg. In this operation, the Liquid Apogee Motor (LAM) was fired for duration of 1 hour 55 minutes. In the process, about 362 kg propellant was utilised.

This orbit raising operation began today at 0428 hrs IST by commanding the satellite from ISRO's Master Control Facility (MCF) at Hassan, Karnataka. GSAT-10 is in good health. The current orbital parameters of GSAT-10 are:

It may be recalled that GSAT-10 satellite was launched on September 29, 2012 on-board Ariane-5 launch vehicle from Kourou, French Guyana.

The Second orbit-raising manoeuvre is planned in the afternoon of October 1, 2012.

So GSAT-10 is on the way to final destination. :tup
Next movement by afternoon of October 1, 2012. :sp

What the satellite brings


TRANSPONDERS:

30 communication transponders - 12 in Ku-band, 12 in C-band and six in extended C-band. The ISRO is currently leasing 95 foreign transponders to meet domestic demand. The INSAT/GSAT system has 168 transponders.

WHAT IT MEANS FOR DTH:

The Ku band is vital for seven DTH TV operators and thousands of VSAT operators who provide phone and Internet broadband connections. Public and private telephone and television providers also use the C band.

GSAT-10 also has the second GAGAN payload which augments or finetunes the US GPS signals into far more accurate readings. GAGAN, a venture of the Department of Sapce and Airports authority of India, is primarily meant to benefit airlines and their aircraft flying into and out of India. GSAT-8, launched in May 2008, carried the first GAGAN payload.

HEALTH CHECK:

"MCF took over command and control of the satellite immediately after the injection. Preliminary health checks on various subsystems such as power, thermal, command, sensors, control etc., have been performed and all parameters have been found to be satisfactory. The satellite has been oriented towards Earth and the Sun using the onboard propulsion systems," the agency said.

In the coming days, MCF scientists will perform routine manoeuvres to "raise" the elliptical orbit into a circular orbit with 24-hour rotation around the Earth and fixed at 83 degrees East slot over the Indian region at 36,000 km above ground. They will do this by firing the apogee motors on board the satellite in three steps.

Later the antenna, solar panels and other instruments will be deployed and switched on.

Built for 15 years, GSAT 10 will be co-located with InSAT-4A and GSAT-12.

Lets Hope,Today they will place GSAT-10 in GEO successfully on afternoon.
All the best ISRO. :hrt :win
