South Asia Satellite
The South Asia Satellite (designated GSAT-9), formerly known as SAARC Satellite, is a geostationary communications and meteorology satellite operated by the Indian Space Research Organisation for the South Asian Association for Regional Cooperation (SAARC) region. The satellite was launched on 5 May 2017. During the 18th SAARC summit held in Nepal in 2014, Indian Prime Minister Narendra Modi mooted the idea of a satellite serving the needs of SAARC member nations as a part of his neighbourhood first policy. Afghanistan, Bangladesh, Bhutan, Maldives, Nepal and Sri Lanka are the users of the multi-dimensional facilities provided by the satellite. Pakistan "offered technical and monetary support" which India rejected saying that it wanted the project to be a "gift" and multi-national collaboration would be time-consuming. Pakistan later on declined to participate in the project citing India's refusal to collaboration and security reasons. Afghanistan too was initially non-comm ...
