Abstract:

Several significant extensions to the AFCRL program SAGA Short Arc Geodetic Adjustment have been implemented and tested. These include improved corrections for tropospheric refraction capability of exercising on option the precise NWL ephemeris as defined by minute vectors automatic detection and removal of cycle count errors an option for processing Geoceiver observations as if they were Intermittently Integrated Doppler IID observations an option to exercise base line constraints expressed in terms of geodesic azimuths and distances an option to define the coordinate system of the tracking net by means of G. Blahas Inner Adjustment Constraints an option to recover relative timing synchronization between stations independently of satellite timing signals extension of the orbital integrator to accommodate an earth potential defined by spherical harmonics of arbitrarily high degree and order n,m. By virtue of these extensions SAGA has become a more accurate and more versatile tool for satellite geodesy. Author
