Low-power GNSS chipset solutions provider etherWhere has partnered with Xona Space Systems to develop a receiver that tracks Xona’s multi-frequency PULSAR signal. PULSAR, a next-generation position, navigation, and timing (PNT) service, is provided by a constellation of small, powerful low Earth orbit (LEO) satellites that are 20 times closer to Earth than existing GPS.

As 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.

The 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.
