Fast, precise Global Navigation Satellite System (GNSS) positioning depends on how well models describe the ionosphere, the electrically charged region that bends and delays satellite signals.

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 ...

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 ...

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.
