Abstract
The Planetary Ranging Operational Program is now in use at DSSs 12, 48, and 68. It provides ranging capability to several AU. The program also monitors changes in the charged particle density due to diurnal variations in Earth’s ionosphere and solar outbursts. The charged particle measurement is used to correct the doppler data. Both outputs contribute to the more precise orbit determination required for multiple encounter and orbiter missions.
