Abstract
Current ranging systems of the Deep Space Network estimate the range to a spacecraft by measuring the phase of a square-wave range code after its roundtrip from station to spacecraft and back, Distortion of this waveform, in the form of phase-shifts of the harmonics of the square wave, can seriously degrade ranging accuracy. In this report, we show that such degradation can be largely eliminated by zonal filtering the range code to only its sine-wave fundamental at no net cost in ranging signal power or accuracy.
