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.

As demand grows for high-precision navigation in autonomous vehicles, mobile mapping, robotics, and other real-time ...

Self-driving cars need to know exactly where on the road they are located at all times. A new invention could revolutionize the development of driverless vehicles—and give us more accurate GPS on our ...
