A Superconducting Microwave-Cavity Lock for the International Space Station

Abstract
With the approach of the Space Station era new interest has been kindled
in performing fundamental physics experiments in space with time scales
of months.Recently a superconducting microwave cavity clock experiment
(SUMO) was selected for flight to perform experiments in relativity.The project has four main goals: an improved test of Local Position
Invariance, improved Kennedy-Thorndyke and Michelson-Morley type
experiments,and an enhancement of the performance of atomic clocks
being developed elsewhere for use on the space station.In order to take
full advantage of the various clocks being developed, they will need to
be linked by laser telecommunication.
