Abstract:

Scientific information from the artificial earth satellites will be transmitted to the telemetry systems located at each of the Minitrack stations. The telemetry receiver will amplify the received signals with th e addition of as little receiver noise as possible and convert the information to a form which permits demodulation and subsequent analysis. The receiver is of the doubleconversion type with crystal-controlled local oscillators. Three pre-detection bandwidths are available which provide a means of increasing the output signal-to-noise ratio for those experiments in which the information bandwidth is less than the maximum. Grounded-grid preamplifier circuitry is employed to achieve stability and a low noise figure. Author
