A NAVIC Enabled Hardware Receiver for the Indian Mass Market

Domenico Di Grazia, Damien Cardineau and Fabio Pisoni

Abstract:	The Indian Regional Navigation Satellite system (IRNSS, also named NAVIC) is an autonomous regional satellite navigation system developed to guarantee autonomous positioning to the Indian region. The constellation has been completed on April 2018 with the launch of IRNSS-1I and counts, at the time of writing, seven operational satellites. The demand for compact and power efficient devices, capable of receiving NAVIC satellites, both standalone and in addition to other constellations, is expected to increase in the coming years fostered by Indian Automotive Industry standards adoption. In this context, the paper describes the architecture and performances of a GNSS hardware solution designed for the automotive and mass market, based on the STA8090 “Teseo III” GNSS chipset and the new STA5635 Universal GNSS Front End. Functional details of the proposed solution are reported herein. Tracking sensitivity, startup performances and position accuracy are measured for IRNSS standalone and in combination with GPS. The benefits of using a combination of L1 and L5 signals for positioning and navigation in the urban canyons is outlined. Raw observables, including Carrier Phase, are also qualified.
