Global Navigation Satellite Systems Engineering, Policy, and Design
For decades, artificial intelligence and machine learning have advanced at a rapid pace. Today, there are many ways artificial intelligence and machine learning are used behind the scenes to impact our everyday lives, such as social media, shopping recommendations, email spam detection, speech recognition, self-driving cars, UAVs, and so on.

The second of a two-part article explains how an initial system using existing Earth-GNSS constellations may be augmented with dedicated lunar orbiting satellites as well as lunar beacon ranging sources. A gradual deployment leads to a full autonomous lunar navigation system.
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.
The SiriusXM satellite radio network now broadcasts GNSS corrections from Trimble’s RTX service. New cars sold in the contiguous U.S. and Canada equipped with SiriusXM’s Gen8 satellite chipset will be able to receive RTX GNSS corrections, without the need to access a cellular network, thus enabling high-accuracy positioning, a key component of autonomous on-road applications.

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.
Ten companies active in positioning, navigation, and timing (PNT) have formed the Open PNT Industry Alliance. The coalition seeks to fortify economic and national security by supporting government efforts to accelerate the implementation of backup PNT capabilities for critical infrastructure.
