Abstract:

This report deals with the ideas behind the design and operation of the APL Satellite Telemetry Data Processor designed by SSD-1 for use as test equipment during the satellite checkout, launch and early orbit operations. The Processor takes an input of PAM Pulse Amplitude Modulation, PDM Pulse Duration Modulation, and PCM Pulse Code Modulation information and prepares it for print-out, further processing, or display by means of lights, automatically finding bit and frame synchronization. The unit was designed during the summer of 1962 and it has been used with four different satellites. One of these satellites is the S-66. The accuracy of the PAM print-out is usually better than one per cent when used within the telemetry system, which includes a radio link. Author
