| Abstract | The main goal of this work is to compare the accuracies of transmitters geolocation results obtained by Argos system (France) and by INPE´s system, using the algorithm for geographic location of transmitters developed in Sousa et al. (2001). Location data (time and Doppler shift) were supplied by Argos control center staff, except for the satellites ephemeris. This comparison was performed using NOAA satellites, in order to verify the robustness of the location procedure compared to the supplied ARGOS results, which are claimed to have a precision of about 100-500m. The ARGOS control center uses precise orbitography transmitters data with sophisticated orbit determination of the NOAA satellites, besides having the full Doppler curve data available for processing and geo-location. On the other hand, INPE has developed a simple scheme for processing the sparse Doppler data obtained through the Brazilian network of DCPs (Data Collecting Plataforms). The ephemeris is recovered via Internet, the orbit is propagated by the SGP4 NORAD model (Hoots, 1980), and the Doppler data is modeled and processed using a robust Householder orthogonalization for the least squares processing procedure (Lawson, 1972). The results obtained using such data and two-line orbit elements, obtained at www.celestrak.com, show as expected a fair degree of consistency in terms of precision compared to results of Argos system. |
