Abstract This report describes a digital ranging modem implementation based on side-tone ranging concepts. The ranging technique implemented and tested in the DOT/TSC avionics laboratory has direct application to the AEROSAT surveillance system. The performance of a breadboard unit was observed in the laboratory as well as under actual aeronautical and maritime experiments conducted with the NASA ATS-6 satellite. The technique demonstrated an acquisition probability of 0.98 for a signal-to-noise power density ratio, C/No, of 37 dB-Hz. The ranging precision of the modem (for C/No>50 dB-Hz) is less than 66 meters. Circuit schematics, test data, test results and analyses are included in this report along with recommendations for future applications of the demonstrated hardware.
