Abstract
The DSN Tracking System Mark III-77 currently being implemented at the Deep Space Stations will automatically provide doppler noise (rms phase jitter) computed concurrently over three evenly spaced decades of data sample interval and associated time-scale: Data sample interval, sec Time-scale, sec 0.1 1.8 1.0 18.0 10.0 180.0 100.0 1800.0 It is here suggested that these data translate directly into “average” phase fluctuation spectra, and hence represent a new and convenient source of radio science information. Temporal phase fluctuation spectra derived from Viking and Helios doppler noise data yield a power law relationship with frequency as follows: Py (f)~f- 2” for the following approximate range of frequencies:
