Abstract

This article study the performance enhancement that can be achieved by the introduction in the system of inter-satellite link (ISL) technology in GNSS systems. The use of ISL can improve both dissemination latency from 100 to 5 minutes (or lower) and determination accuracy from values below 65 cm (67%) to values well below 10 cm (67%). In this paper an OD&TS scheme for processing both the classical space-to-ground L-band observations and the new space-to-space ISL-band observations and the performance results achievable are presented.
