Smartphone-based GNSS Positioning – Today and Tomorrow

This article reviews some of the recent results analyzing the feasibility of carrier-phase based positioning with smartphone data and highlights limitations largely arising due to the poor antenna quality. It shows how they might be overcome by antenna calibration or coupling to the phone’s inertial sensors. The goal is to perform a successful RTK positioning with the smartphone-quality data.

For PNT Integration, Timing Is Everything

GPS + inertial + camera + LiDAR + baro-altimeter = a very precise measurement, right? Not when the respective sensor output timings lack proper synchronization. Only when each piece of data carries an accurate timetag can they together enable optimal performance in multi-sensor fusion systems.
