"Laser Ranging Makes GPS Satellites More Accurate" by @hackaday - Laser retroreflector on newest #GPS satellite is the first of what will be on all upcoming GPS satellites. Similar reflectors left on the Moon by Apollo astronauts allow scientists to measure distance to the Moon to the millimeter. Same use for GPS satellites will reduce error in their estimated trajectory, and improve #positioning, #navigation & #timing #PNT derived from them. https://hackaday.com/2026/03/29/laser-ranging-makes-gps-satellites-more-accurate/ #GNSS #satellite #space

Laser Ranging Makes GPS Satellites More Accurate

Although GNSS systems like GPS have made pin-pointing locations on Earth’s sphere-approximating surface significantly easier and more precise, it’s always possible to go a bit further. …

Global Navigation Satellite System ist verwundbar. Quantenbasierte PNT-Systeme versprechen Abhilfe – doch ihre Robustheit gegenüber zukünftiger elektronischer Kampfführung ist kaum erforscht.
Die @Cyberagentur veröffentlichte Ausschreibung zum Forschungsprogramm EloQa Gesucht: Übersichtsstudie zu Risiken, Angriffspfaden, Schutzmaßnahmen quantenbasierter Navigation.
