Like any other communication satellite, the
IAF’s GSAT-7A, too, has to operate within a
specific frequency band. The bands are
allocated by the International
Telecommunication Union. Sources in the Indian Space Research
Organisation (Isro) told DH that there was a
delay in obtaining the frequency for GSAT-7A
whose launch has been delayed by many
years. The process to identify the frequency
took time to ensure the allocated frequency doesn’t interfere with the satellites operating in
the nearby frequency ranges. Isro is looking at a launch window towards the
end of 2017 if the scientists are able to ready
another indigenous GSLV flight by then. GSAT-7A will not be carried by GSLV Mark-III in
its next developmental flight scheduled for
March 2017, sources said. It would carry
GSAT-19E, another civilian satellite. GSAT-7 (Rukmini) and GSAT-7A are India’s only
two dedicated military satellites made for the
Navy and the IAF. While the Navy has had its
communication satellite up in the sky since
August 2013, the IAF is still waiting for one of
its own. The 2,650-kg naval satellite has transponders in
Ku-band, S-band and an ultra-high frequency
band to communicate with the submarines. It
operates from an orbital location of 74 degrees
east and has a life span of 15 years. GSAT-7A, on the other hand, will have
transponders only in the K-band, the Isro
sources said, because of the IAF’s requirement. With the Air Force increasingly moving
towards network-centric warfare using a
range of platforms like fighter jets, UAV and air-
borne radars, communication support from a
satellite has become absolutely essential.
