The Indian Air Force’s wait for its own satellite is getting longer because of a delay in obtaining a dedicated frequency band from the international regulatory body.

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.

NEW DELHI: With tensions rising on India's borders in recent years, first with Pakistan in 2016 following the attack on an Army camp in Uri and now with China in Doklam, the government is mulling a dedicated satellite bandwidth for the Border Security Force (BSF), Indo-Tibetan Border Police (ITBP) and Sashastra Seema Bal (SSB) for better border surveillance.

The idea is to enable the border guarding forces to monitor the movement of Pakistani and Chinese troops in real time, track terrorist infiltration, map terrain and communicate effectively in remote areas, besides assessing the strength of soldiers and artillery deployed by neighbours near the border in case of a stand-off.

Sources in the government told TOI that top bureaucrats in the home ministry recently held several rounds of meetings with BSF, ITBP, SSB and ISRO officials, during which it was discussed whether a single satellite would be enough to monitor activities on the borders or if each force needed to be provided a dedicated satellite.


It was felt that command, control, communication, surveillance, intelligence and reconnaissance abilities of border security forces -- the first line of border defence -- needed to be made impregnable, they said. The proposal is in the initial stages but sources said the government was serious about it.


TOI's attempts to get comments from the MHA and senior officials of border guarding forces remained unsuccessful.

An officer, who did not want to be named, said, "Satellites can play an important role in border management, and India has some of the best ones in Asia. While defence forces already use space technology, border forces depend on intelligence shared by central agencies like IB, RAW and National Technical Research Organisation. They also face poor communication issues in areas like Ladakh, Sikkim, Arunachal Pradesh and Kashmir Valley.
With satellite technology for real-time information, future incidents can be better dealt with."

India shares over 15,000km of borders with Pakistan, China, Bangladesh, Nepal and Myanmar. The armed forces currently use 13 ISRO satellites to watch land and maritime boundaries.

The Navy has a dedicated military satellite, Gsat-7 or 'Rukmini' which monitors the Indian Ocean Region as it has a nearly 2,000 nautical mile "footprint".

The Cartosat-2 series advanced remote sensing satellite, launched on June 23, has added teeth to India's military surveillance capabilities as its high-resolution PAN camera can cover a swathe of 9.6km and its spatial resolution is less than one metre.

The MHA is also providing border forces with modern electronic surveillance equipment like night-vision devices, thermal imagers, battlefield surveillance radars, direction finders, unattended ground sensors and high-powered telescopes.
