COMMUNICATION SYSTEMS ANALYSIS FOR LIGHTWEIGHT ROVING LUNAR VEHICLE

Abstract

Efforts were made to determine the transmitter power requirements as a function of data transmission rate for the Prospector moon-to-earth TV link. An analysis is presented based on the utilization of PCM-PS modulation at an RF carrier frequency of 2250 mc. The ground based receiver station utilizes the DSIF equipment. The video input is obtained from the output terminals of an image orthicon camera located aboard the tank. The maximum data rate assumed is 1.5 x 10 to the 6th power bits/sec, i.e., 1000 vertical lines, 500 horizontal lines and 8 levels of grey. The video output from the communications system consists of a train of binary pulses that will have a digit error of 1 in 100, 000. (Author)
