Signal Communication by Orbiting Relay Equipment

NSSDCA ID: 1958-006A-01

Mission Name: SCORE


This first communications satellite experiment consisted of 2 identical communications repeater terminals mounted in the guidance pods along the sides of the launch vehicle. The experiment was to test the feasability of, and explore problems associated with, using satellites for communications purposes. No modulation was received on the carrier wave from experiment package no. 1. Voice and teletype messages were sent and returned in real time, and also from experiment tape recorder no. 2. The tape recorder was loaded with new material 28 times and failure finally was due to battery depletion. The experiment receiver and transmitter operated at 150 to 132 mHz, respectively.
