BeiDou System (BDS) Triple-Frequency Ambiguity Resolution without Code Measurements
Feng Yu Chu,Ming Yang +1 more
TL;DR: A modified phase-only method that only uses triple-frequency phase measurements to achieve BDS ambiguity resolution is proposed and generally performs better than the phase-code ambiguity resolution, but the improvement is subject to phase noise and satellite geometry.

A Long-Term Broadcast Ephemeris Model for Extended Operation of GNSS Satellites
TL;DR: A tailored force model for numerical orbit propagation is proposed that offers high accuracy but can still be used in real-time environments and enables adequate quality for a rapid first fix or contingency navigation in case of lacking ground segment updates.
