Current atomic clocks used in the GNSS are relatively compact ... 5m and weigh hundreds of kilograms. Given satellite space ...

The study's results could advance user-centric GNSS and network-centric ... which replaced traditional atomic clocks. Simulations of a four-satellite system demonstrated that QS achieved high ...

Satellite orbits and clocks are determined using observation data from a global GNSS network together with other parameters such as station coordinates, earth rotation parameters and troposphere ...

This successful demonstration makes it plausible that future lunar missions, whether in orbit or on the surface, could use Earth’s GNSS satellites to navigate and position themselves with.

Using the Global Navigation Satellite System (GNSS ... forces also mean that Earth-based clocks appear to lose 58.7 microseconds per Earth day. “An atomic clock on the moon will tick at ...
