Abstract : A doppler ranging technique for determining the height and horizontal range-time histories of flight of a sounding rocket is described. Two stable oscillators operating at the same frequency are employed. One oscillator is carried in the rocket and its output is telemetered to the ground. The other oscillator is used as a ground-based reference located at the telemetry receiving station at the launch site. The method is primarily of interest for use at remote launching sites where normal range tracking facilities do not exist. The results of a number of trials of the method with Black Brant II rockets launched at the Churchill Research Range are discussed. They indicate that an accuracy of plus or minus 1 km for apogee height can be obtained. (Author)
