The results are reported of the ATS-6/GEOS-3 and the ATS-6 NIMBUS-6 satellite-to-satellite orbit determination experiments. NASA intends to use the tracking data relay satellite system for operational orbit determination of NASA satellites. Hence, in the near future, satellite-to-satellite tracking data will be routinely processed to obtain orbits. The satellite-to-satellite tracking system used in the ATS-6/NIMBUS-6 and ATS-6/GEOS-3 experiments performed with a resolution of 1 to 2 m in range and less than 1 mm/s in range rate for a 10-s averaging. A Bayesian least squares estimation technique utilizing independent ranging to the synchronous relay satellite was determined to be the most effective procedure for estimating orbits from satellite-to-satellite tracking data. The use of this technique yields estimates of user satellite orbits which are comparable in accuracy to what is usually obtained from ground based systems. 相似文献

Two NASA laser satellite tracking systems on opposite sides of the San Andreas fault will be used in an experiment to measure the gross relative motion of the tectonic plates of North America and the Pacific during the next several years. Initial sites at San Diego on the Pacific Plate and Quincy, California, on the North American Plate, nearly 900 km apart, have already been selected and occupied, and other sites further south are proposed. Each site is occupied for two or three months per year and simultaneous precision laser distance measurements to the Beacon Explorer-C satellite from these sites will be used to determine the relative position of one site with respect to the other. Results of a simulation of this experiment in which a pair of sites are reoccupied annually for about eight years indicate an eventual accuracy of about 0.5 cm/yr in the average plate motion. The results of a preliminary three-month observing period in 1972 indicate a precision of about 15 cm in the chord distance between the San Diego and Quincy sites. 相似文献
