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 ...

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.

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. A new ...

Audio is not provided for this article. Oscilloquartz began a collaborative tech validation alongside Tupaia, showing that carriers and enterprises can attain highly accurate GNSS location by ...

Satellite-based positioning systems exploit constellations of Earth-orbiting transmitters to determine the three-dimensional location and time of a user receiver. Each satellite continuously ...
