 Twenty-two years after the first navigation satellite was put into orbit, another country is joining the movement. India recently announced they will be launching seven satellites in the next four to six years. The seven satellites will be the foundation of the Indian Navigation System or INS which will cover only India and its regions of military and civilian interest. Today, India primarily depends on the United States' Global Positioning System (GPS) for satellite access. After agreeing to a deal, India also uses GLONASS, the Russian satellite system. However, both GPS and GLONASS (Global Navigation Satellite System) are operated with their own countries' interest in mind, prompting India to venture into satellite navigation. The Indian satellites will be placed at a higher orbit than current ones. The placement will provide a larger signal footprint using less satellites. While the current GPS satellites are for civilian use only, INS will be utilized for military purposes. After all, India does not want to be left stranded during times of crisis or conflict because of their dependency on other countries. Moving forward, India hopes these satellites will also serve as a new source for telecommunications, public safety and identification of disaster areas. |
