Timing performance and stability characterization of an In house realized NavIC Timing Receiver

Abstract

Navigation with Indian Constellation (NavIC), also known as Indian Regional Navigation Satellite System (IRNSS), is the Indian regional satellite navigation system. A NavIC Timing receiver is a type of user receiver which realizes NavIC system time on ground by steering its internal oscillator to the NavIC system time. These receivers act as NavIC based time reference. In order to reduce the dependency on other GNSS based timing references, a NavIC Timing receiver has been developed in-house at ISTRAC for use at all ground facilities. This paper provides an assessment of the timing performance and stability characterization of this NavIC Timing receiver.
