Since the dawn of GPS, researchers have worked to improve the accuracy of estimated positioning, navigation and timing (PNT) from the receiver-derived pseudorange, carrier-phase and Doppler ...

GNSS researchers presented hundreds of papers at the 2023 Institute of Navigation (ION) GNSS+ conference, which took place Sept. 11-15, 2023, in Denver, Colorado, and virtually. The following four ...

Precise Point Positioning (PPP) is widely used for high-accuracy navigation, but broadcast ephemeris from the BDS-3 system still suffers from hourly discontinuities that degrade real-time performance.

In an era of growing demand for real-time precision navigation, researchers have unveiled a powerful leap forward in satellite-based positioning. Leveraging new-generation Global Navigation Satellite ...

Precise Point Positioning (PPP) has long held promise as a standalone, high-accuracy positioning technique, but its slow convergence and complexity in ambiguity resolution have limited widespread use.
