A time comparison experiment performed by SSRA system via ATS-1
Abstract
A time comparison experiment between the Kashima, Japan ground station and the Rosman U.S. ground station was performed from Aug. 19 to 28, 1975 using the ATS-1 satellite. The communication system employed was SSRA (Spread Spectrum Random Access), operating in the SHF band, and both ground stations used commercial cesium clocks with high performance tubes. An error analysis was performed, with attention drawn to instrument errors, errors due to satellite drift, errors due to system delays, and errors due to radio wave refraction in the ionosphere. Results showed that the SSRA system can perform the satellite time comparison with very high resolution, better than a few nanoseconds.
