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.

Auburn University Autonomous Tiger Racing, sponsored by Safran Electronics & Defense, recently completed a full lap with its autonomous Indy racecar at the Barber Motorsports Park in Birmingham, Alabama. It was the first time a vehicle participating in the Indy Autonomous Challenge (IAC) completed a lap on a professional track in the United States without any human intervention.
