UrsaNav and ADVA have conducted an enhanced long-range navigation (eLoran) field trial using UrsaNav’s eLoran receiver and ADVA’s Oscilloquartz grandmaster clock technology. The successful demo showed that eLoran offers a robust and reliable backup for GPS and other GNSS and could be used to provide an assured position, navigation, and timing (PNT) service.

NASA has awarded a contract to the University of Michigan for the Cyclone Global Navigation Satellite System (CYGNSS) for mission operations and closeout. A constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists’ ability to understand and predict hurricanes. The total value of the contract is approximately $39 million. The CYGNSS Science Operations Center is located at the University of Michigan.

eMobility services that provide on-demand eBikes and eScooters rentals are fast growing alternatives to traditional transportation modalities. As they are affordable, convenient, and very green, eMobility services will continue to grow in popularity. This article presents some of the challenges and useful solutions to accurately track eBike and eScooter location in the real world.
The Department of Transportation (DOT) submitted its “National Timing Resilience and Security Act: Roadmap to Implementation” report to Congress in mid-January. Following a competitive application process, demonstrations and review of 11 candidate technologies to back up GPS capabilities, the DOT concluded that “none of the systems can universally backup the positioning and navigations capabilities provided byGPS and its augmentations.” However, “all vendors demonstrated some PNT performance of value, but only one vendor, NextNav, demonstrated in all applicable use case scenarios.”

According to a statement on the UK Government’s official website, as of January 1 the United Kingdom will cease participation in the European Galileo and European Geostationary Navigation Overlay Service(EGNOS) programs. British citizens and other private users are not affected, apparently: “devices that currently use Galileo and EGNOS, such as smart phones, will continue to be able to do so.”

A satellite launching in November will use GNSS – Radio Occultation (GNSS-RO) to collect highly accurate global temperature and humidity information as an aid to more accurate and more advanced weather forecasting. Developed by NASA’s Jet Propulsion Laboratory (JPL), the spacecraft’s GNSS-RO instrument tracks GNSS satellite signals to measure the physical properties of Earth’s atmosphere.
