Since 1975, the Defense Mapping Agency (DMA) has been computing precise orbits for the Navy navigation satellites, OSCAR series. In mid-1981, DMA began computing precise orbits for the NOVA-1 satellite and, in early 1985, for the NOVA-3 satellite. Currently, DMA determines precise orbits for the three OSCAR and two NOVA satellites which comprise the TRANSIT System. This paper presents a comparison of computational results for these satellites with regard to orbit accuracy, time (oscillator) stability, and polar motion. The comparison is made for results obtained for 1985. (Author)
