India is planning to expand the regional satellite navigation system NavIC. Key facts The Indian Space Research Organization (ISRO) is currently planning to expand the Navigation with Indian Constellation (NavIC). It had sought the government’s permission to launch 12 additional satellites into the Medium Earth Orbit (MEO) for this purpose. Placing NavIC satellites in MEO ..
Recently, China has successfully launched its first geostationary BeiDou-3 satellite ‘G1Q’ into high orbit (about 36,000 km above the Earth) to boost its home-grown BeiDou global satellite navigation system. It was launched from the Xichang Satellite Launch Centre in the southwestern Sichuan Province. In a geostationary orbit, following the Earth’s rotation, it will view the ..

Russia has successfully launched a Glonass- M positioning satellite by using a Soyuz-2.1b carrier rocket from the Plesetsk space center on June 17, 2018. The Glonass network provides real-time positioning data for surface, sea and airborne objects around the globe, at an accuracy reportedly at par with the U.S. Global Positioning System.
The Indian Space Research Organisation (ISRO) has developed an indigenous atomic clock that will be used in navigation satellites to measure precise location data. It is being developed by the Ahmedabad-based Space Applications Centre (SAC). This clock is currently undergoing a series of qualification tests. Once it successfully clears all tests, the desi atomic clock ..
