NavIC tri-band (L1, L5, S) SPS simulator.

With an objective to become self-reliant with the use of Satellite based Navigation, India has undertaken the initiative for the development of its own constellation of Navigation Satellites named as Navigation with Indian Constellation (NavIC). This paper presents the design and development of the NavIC L1, L5 and S Band SPS Simulator, developed at Space Applications Centre (ISRO) for the realization of NavIC Receivers and for the proliferation of NavIC based applications for usage throughout the country. This paper describes the major capabilities of the Simulator with all the supported features. This paper also presents the signal structure of NavIC for the various bands and covers the evolutionary journey of the NavIC program. With the rising demand for Navigation Simulators, the market size is expected to be 430 million USD by 2030 as per market survey. The GNSS Navigation Simulators in general and NavIC Simulator in particular with RF signal generation capability is a highly expensive product, which may not be economically viable for small industries and academic institutions. The development of this NavIC Simulator will help various Indian Academic Institutions and Industries to start their independent Navigation Receiver development activity and help assist researchers to work in the Indian Navigation Technology.
