Initial Analysis and Modeling Results from the Polar Orbiting Geomagnetic Survey (POGS) Satellite
Abstract
The spatial and temporal character of fully calibrated geomagnetic data collected on selected orbits of the Polar Orbiting Geomagnetic Survey (POGS) satellite mission during the first 6 months of 1991 is analyzed with respect to a preliminary, degree 12 spherical-harmonic magnetic field model derived from selected POGS data collected during January and February 1991. The accuracy of global models derived from these data depends on the vector magnetometer calibrations, thermal corrections, satellite magnetic mapping, and the time syncing of the satellite's quartz clock with respect to the satellite's ephemeris, which is referenced to Universal Time (UT) and which is supplied by the Defense Mapping Agency's tracking network (TRANET). The calibration and correction factors applied to the POGS data set are fully documented Additionally, the current status of the POGS satellite and the corresponding data reduction and distribution efforts along with the current status of subsequent POGS experiments, which are part of the Defense Meteorological Satellite Program (DMSP) Block 5 and Block 6 satellite missions known as DMSP/ POGS follow-on experiments, are presented.
