NASA is seeking PNT requirements for advanced air mobility when GPS is not available, but the ultimate solution may come in many forms.
At the recent FAA AAM Summit, NASA’s Parimal Kopardekar, one of the main movers in the advanced air mobility field, was asked to name some of the top operational challenges facing AAM in the near term.

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.

The European Agency for the Space Program (EUSPA) is moving forward with its rollout of the free Galileo high accuracy service (HAS). Speaking at the recent HAS Days event in Spain, EUSPA’s Carmen Aguilera said, “Galileo HAS is user driven, as is the case for all European space programs. Our goal is to make sure that the services we are delivering are tailored to meet the needs of the users and the industries that will employ them in their businesses.”
