Data Reduction Program Documentation ALTPOD (Effective: August 1971)

Abstract

ALTPOD produces punched metric data for input to non-real time precision orbit determination program for both exoatmospheric and re-entry trajectory determination. ALTPOD automatically corrects the data for known biases and tropospheric refraction. Optional corrections for off-axis position and ionospheric refraction are available. Ionospheric refraction corrections should be applied when the target is in or above the ionosphere. Off-axis corrections should be made when the angular rates are sufficient to cause the antenna to lag. Range error, signal-to-noise ratio, and the standard deviations of range error and azimuth and elevation offsets are listed to help evaluate non-real time precision orbit determination program results.
