Abstract:

The object of the contract was to investigate satellite-to-satellite tracking for orbit improvement and determination of a 1 degree x 1 degree gravity field using actual GEOS-C data. Studies were conducted at a low level of effort in order to familiarize personnel with the characteristics of the data and to obtain a limited check on the principal analysis. Results of simulations designed to accomplish the goals of the contract are presented. These simulations were made awaiting the launch of GEOS-C and the release of the initial tracking data. GEOS-C state vectors were determined from NSWC range difference data. The vectors are for 13 revolutions observed during the period from 27 April 1975 to 3 May 1975.
