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.

The United States Federal Aviation Administration’s (FAA) Wide Area Augmentation System (WAAS) uses Hexagon | NovAtel technologies, including reference receivers and signal generators, to provide the accuracy and integrity necessary to safely operate civil aircraft. Here’s a look at the updated technologies and how they enable GPS as a safety of life service for aviation.
The European GNSS Agency (GSA) has started testing the Open Service Navigation Message Authentication (OSNMA) feature in the Galileo signals.

In 2018, when the UK’s post-Brexit involvement in Galileo was still a point of contention between London and Brussels, UK ministers set aside £92m to study the feasibility of building a sovereign satellite-navigation system. Almost immediately, the UK Space-Based Positioning Navigation and Timing Program (SBPP) became something of a political football, or soccer ball if you prefer. Critics and supporters chimed in vehemently at any piece of news. Why an independent UK PNT system might be necessary remains a reasonable first question for some observers.
