By Inside GNSSThe recent spotlighting of alternative positioning, navigation and timing technologies by weighty bodies such as the European Commission and the European Space Agency is causing more than a stir among the concerned communities, with both public and private interests now readying themselves to move beyond conventional GNSS for critical applications.
By Peter GutierrezIn the past decade, there has been a sharp increase in GNSS outages due to deliberate GNSS jamming. Receivers in LEO are uniquely situated to detect, classify and geolocate terrestrial GNSS jammers. This article explores two-step and direct geolocation of terrestrial GNSS jammers from LEO.
By Inside GNSSThis research analyzes the wide-area 2022 Texas GPS jamming incident using data from airborne receivers through Automatic Dependent Surveillance – Broadcast (ADS-B) and ground receivers at Continuous Operating Reference Stations (CORS).
By Inside GNSSThe new blockchain-based, decentralized CORS reference network provides low-cost access to triple-frequency full-constellation correction signals for centimeter accuracy, while also allowing users to earn financial rewards for contributing qualified CORS data back to GEODNET.

Building on decades of GNSS positioning and algorithm development expertise, Waypoint 9.00 includes BeiDou Phase III support and a refreshed, streamlined GUI for users to import, process and export their data faster and more efficiently.
By Inside GNSSAs of August, 2023, operational Galileo GNSS satellites, with some exceptions, have been updated and are now transmitting an improved I/NAV message. Users will see an enhancement in the Galileo E1 Open Service (OS) performance in terms of robustness and a significant reduction in time to first fix in challenging environments, with both unassisted and assisted GNSS. Backward compatibility is assured, with no impact on legacy receivers and low complexity implementation within OS receivers.
By Peter GutierrezThe latest safety award for Rivian is an Insurance Institute for Highway Safety for the R1S as a Top Safety Pick+ for 2023. It accomplishes this and other safety advances with its Driver+ ADAS (advanced driving assistance system), which integrates a set of sensors along with driver attention, GNSS, and IMU modules. At AutoSens Detroit 2023, Abdullah Zaidi, Engineering Lead and Senior Manager at Rivian, presented his take on the state and near future of ADAS sensors including the benefits of adding lidar and the importance of better localization sensors for Level 3 systems.
