The Cruise Test was conducted shortly after Launch while the spacecraft was still close to Earth and solar system plasma effects were minimal. This is a good measure of the end-to-end system performance with minimal perturbations from the propagation path. It also provides Allan Deviations at the longest integration times. The AB-1 Occultation curve shows end-to-end performance near maximum Earth-Mars separation (1998-03-23). The Mapping Occultation curve shows Allan Deviation measured near the smallest Earth-Mars range but with the HGA deployed, which was not the case for the other two curves. Figures ======= Plot(s) illustrate some of the points made in the text. Each plot is a PostScript file, created and printable on our SOPC. For report text file HEAydddC.TXT Figure N will be labeled HEAydddC.PSN and sent as the N+1st e-mail message of a set. We assume that you can strip off the e-mail headers and either display or print copies of the figures on a machine in your area. People who have indicated that they cannot handle these files by e-mail are not included in the e-mail distribution of figures.
