Defence satellite

India's first exclusive defence satellite GSAT-7 was successfully launched by European space consortium Arianespace's Ariane 5 rocket from Kourou spaceport in French Guiana in August 2013, giving a major push to the country's maritime security. The Indian Navy is the user of the multi-band, home-built communication spacecraft, which is operational. GSAT-7 was designed and developed by the Indian Space Research Organisation (ISRO) and is expected to operate for seven years in its orbital slot at 74 degrees east, providing UHF, S-band, C-band and Ku-band relay capacity. Its Ku-band capacity is expected to provide high-density data transmission facility both for voice and video. This satellite has been provided with additional power to communicate with smaller and mobile (not necessarily land-based) terminals. This dedicated satellite is expected to provide the Indian navy with an approximately 3,500–4,000 kilometres (2,200–2,500 mi) footprint over the Indian Ocean region, and over both the Arabian Sea and the Bay of Bengal region and enable real-time networking of all its operational assets in the water (and land). It also will help the navy to operate in a network-centric atmosphere.
