Global Navigation Satellite Systems Engineering, Policy, and Design
The latest update to Racelogic’s SatGen GNSS simulation software for PC now incorporates Galileo RF simulation.
Designed to create a GNSS RF I&Q or IF data file based on a user-generated trajectory file, the updated software can now accurately simulate the European Galileo GNSS satellite constellation alongside existing GPS, GLONASS and BeiDou RF signal generation.

Our source inside the European GNSS Agency (GSA), which is the EU agency responsible for Galileo services, has told us: “They are working on it. Teams from industry and the Agencies are working 24/7 to restore the Galileo services as soon as possible to their nominal levels. The current estimation is that the services should be restored within 48 hours. In any case, we expect the service to be again nominal before the end of the weekend [13-14 July 2019],” the source said.

Spectrum regulators should hold off on granting a waiver supporting testing of a new UltraWideband (UWB) technology for driverless vehicles until more information is available, the GPS Innovation Alliance (GPSIA) said in comments to the Federal Communications Commission (FCC). In fact the FCC should require a minimum level of information be submitted before considering any UWB waivers or changes to the UWB rules, the GPSIA said.
