Real-Time PPP-Based Monitoring of Galileo-BDS Time Offset Using PPP-B2b and HAS

In multi-GNSS positioning, navigation and timing, the inter-system time offset must be handled explicitly. For Galileo-BDS Time Offset (GBTO), PPP-BCE is limited by signal-in-space errors, and fixing GBTO as a prior is fragile to sub-nanosecond datum and inter-system bias drifts between HAS (GTRF) a...
