Progress of the LASSO Experiment

B.E.H. Serene

Abstract:	The LASSO (Laser Synchronisation from Stationary Orbit) experiment has been designed to demonstrate the feasibility of achieving time synchronisation between remote atomic clocks with an accuracy of one nanosecond or better by using laser techniques for the first time. The experiment uses ground based laser stations and the SIRIO-2 geostationary satellite, to be launched by ESA towards the end of 1981. The first part of the paper is dedicated to the qualification of the LASSO on-board equipment, with a brief description of the electrical and optical test equipment used. The second part gives the progress of the operational organisation since the last PTTI meeting, including the provisional list of participants.
