In the past few months, there have been articles in the press providing information and misinformation in advance of the GPS week rollover that occurred on April 6. Readers were warned to retire obsolete receivers, update software, check with manufacturers, and even perform testing of critical devices.

Curtis Hay is a Technical Fellow at General Motors, where he develops precise GNSS and map technology for safe and reliable autonomous and semi-autonomous vehicles. He has appeared on many international stages, but while he very much enjoys traveling and meeting people in faraway lands, both for work and for pleasure, he knows where home is.

Improvements to GPS performance are often incremental, achieved by squeezing better performance out of existing systems with clever tweaks, smarter analysis and sharper receivers. Then again, every once in a while, there’s a huge leap in the capabilities of the system itself—an advance so big that it makes you appreciate all over again the elegant wizardry of satellite navigation.

The European Union-funded GNSS.asia H2020 project hosted a major roundtable discussion around the theme of “Europe Meets India” at the recent 2019 Munich Satellite Navigation Summit. The event was aimed at promoting cooperation between the GNSS research and industrial communities in Europe and Asia-Pacific.

The Air Force Research Laboratory (AFRL) is considering a contract for research and development of celestial-aided navigation technologies. The primary focus is to develop a Star Tracker that can reliably perform celestial sightings for sensor altitudes between 30,000 feet and 80,000 feet. The goal is to reduce the risks to guidance, navigation and control in GPS-denied environments, especially for operations over feature-poor terrain such as desert, water, snow and ice where existing terrain-aided methods may not be used for position, navigation, and timing (PNT) updates.
