dcterms:description
The LTT payload onboard the Chinese experimental navigation satellite COMPASS-M1 with an orbital altitude of 21500 km launched on April 13, 2007 included dual-SPAD-detector, dual-timer based on TDC device , DSP, power supply and a LRA with the total mass of 7.05 kg (including LRA's 2.45 kg) and the power consumption of 18 W. The time transfer experiment at Changchun SLR station has started since August 2007. The experiment has shown that the time and relative frequency differences between the ground hydrogen maser and the China-made space rubidium clocks have been obtained with the time precision of about 300ps for single measurement and the uncertainty of frequency difference of about 3x10-14 in 2000 seconds. After 17 months orbital flight, the LTT payload has kept its good performance.
