Abstract
GNSS system is a key primary time source for GNSS receiver based PRTC. It provides highly accurate time at tens of nanoseconds to be used by PRTCs in the network. This highly accurate time is obtained by PRTC. The GNSS system comprises control segment, space segment, and user segment. The PRTC is part of user segment. The GNSS-based time is however subject to few error conditions some of which can be corrected for time accuracy while others are inevitable. PRTC provides several mechanisms to correct these timing errors and these include SNR, Elevation Masking, P/TDOP, T-RAIM Masking, Cable delay correction, and multipath mitigation. A good PRTC should provide some of these correction mechanisms to provide highly accurate time source for the network.
