PROJECT ECHO. ANTENNA STEERING SYSTEM,
Abstract
The Project Echo communications experiment employed large, steerable, transmitting and receiving antennas at the ground terminals. It was necessary that these highly directional antennas be continuously and accurately pointed at the passing satellite. This paper describes a new type of special purpose data converter for directing narrow-beam communication antennas on the basis of predicted information. The system is capable of converting digital input data into real-time analog voltage commands with a dynamic accuracy of + or -0.05 degree, which meets the requirements of the present antennas.
