Tehran, Iran: Iran unveiled indigenous satellite navigation system, Nasir 1, during a ceremony held in Tehran, Tehran Times reported. However, unlike other satellite-based navigation system, it has been designed to find the precise locations of satellites moving in orbit.
In the ceremony, Director of Iran Space Agency Hamid Fazeli expressed hope that a special model of the Nasir 1 which can be fitted on spacecrafts would be manufactured by Iranian experts in the near future.
A satellite navigation system is a system of satellites that provide autonomous geospatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to within a few meters using time signals transmitted along a line-of-sight by radio from satellites.
At present, only the US-based GPS and the Russian GLONASS are fully globally operational. China is in the process of expanding its regional Beidou navigation system into the global Compass navigation system by 2020. The European Union’s Galileo positioning system is a GNSS in initial deployment phase, scheduled to be fully operational by 2020 at the earliest. Several countries including France, Japan and India are in the process of developing regional navigation systems.
