A Comparison of ADOS (African Doppler Survey) Point Positioning Results from Various Softwares.

Abstract

The African Doppler Survey project (ADOS) is a multi-national effort to establish primary control (via Doppler satellite observations) on the African continent. There are four Computing Centers under the ADOS project which use three different point positioning programs. These programs are: DOPL79, GEODOP V, and ORB-SPP. The differences observed in the computations using the various softwares were recently investigated. This paper presents preliminary results of this study. Keywords include: Doppler Geodetic Point Position (DGPP), African Doppler Survey (ADOS), Navy Navigation Satellite Systems (NNSS) and Doppler.
