THE VANGUARD SATELLITE COMMAND RECEIVER

Abstract

The earth satellite command receiver has been developed at the request of Project Vanguard. This receiver turns on the satellite instrumentation upon command from a ground-based Minitrack station. The receiver is a VHF double-superheterodyne type utilising a small portion of the 1O8-Mc Minitrack transmitter power as the first local oscillator. The basic design of the various components provides for economical use of satellite battery power and at the same time a reasonable degree of security against accidental interrogation from unauthorized sources.
