Abstract
A technique is presented to determine uplink range change due to line-of-sight charged particles using downlink S/X range and doppler and 2-way DRVID data. The line-of-sight relative charged-particle distribution is first estimated from these data by a pointmatching method. The uplink range change is then synthesized by the weighted sum of the delayed downlink range changes. Simulation analysis shows 2 to 6 cm agreement between the “true” and the synthesized uplink range changes. Demonstration using Viking 1975 radio metric data shows 4 to 22 cm consistency between the uplink range calibration solutions synthesized from S-DRVID and X-DRVID. The consistency is an order of magnitude superior to that equating uplink and downlink effects.
