Bhumish Khudkhudia asked: Is it true that the United States had denied GPS to India during the Kargil War? Did the denial lead to the development of IRNSS by ISRO?

Ajey Lele replies: There is no official information available in the open-source about any such denial by the United States. However, few references to this effect are found in the media. The Kargil war took place during mid-1999, whereas the Indian Space Research Organisation (ISRO) started developing the Indian Regional Navigation Satellite System (IRNSS) around 2010. The first satellite in the seven satellite constellation of the IRNSS was launched in July 2013 and the fifth was launched recently in January 2016
