Geodesy Clocks and Time Transfer with ACES

This Topical Team on Geodesy, Clocks & Time Transfer develops specific applications of clocks in space. They range from measurement of geopotential differences by distant clock comparisons, clocks synchronization and time transfer experiments, generation and distribution of atomic time scales, ranging experiments, in the optical and microwave domain, GNSS time and frequency transfer, study of atmospheric propagation delays. The Topical Team will support the exploitation of the ACES mission in the research areas listed above and contribute to the definition of future scientific missions based on atomic clocks and high- performance time & frequency links in space
