Performance assessment of real-time precise point positioning using BDS PPP-B2b service signal

Advances in Space Research, 2021
Abstract China’s BeiDou Navigation Satellite System (BDS) can provide real-time precise point positioning (PPP) service for users in China and surrounding areas with PPP-B2b signal. In this paper, real-time PPP is assessed and studied based on 8 days of PPP-B2b and BDS/GPS broadcast messages.
