The advent of large LEO constellations is a game-changer for navigation. A key feature of these constellations is their potential to allow simultaneous measurement of Doppler shifts from a large number of satellites.
A framework to seamlessly navigate people from urban road traffic to indoor foot traffic uses the phone’s inertial measurement unit, GNSS chipset and camera, aided by an extended Kalman filter and ORB-SLAM. Tests show the framework performing well in both phases, guiding the phone’s user, behind the wheel on a city street, to a spot in an underground parking garage and walking to a meeting inside a large building.
The latest release from Hexagon promises precise point positioning (PPP) convergence in less than a minute for centimeter-level accuracy on land, air and marine applications around the world.
