OSCAR 5

NSSDCA/COSPAR ID: 1970-008B

Description

OSCAR 5 was a 43-x 30-x 15-cm rectangular prism with reflective stripping applied for temperature control. Four monopole antennae extended from the sides. The satellite carried two tracking beacon transmitters. It carried horizon sensors for determination of spin rate, and had a magnetic attitude stabilization control system. A command system was used to activate the satellite 10-m (29.450 MHz) beacon only on weekends (Friday AM to Monday AM). The seven-channel telemetry reported, by modulation of the beacon signals, the battery conditions, spacecraft temperatures, and horizon sensor responses. Several thousand transmissions were logged and formal telemetry reports received from more than 200 observers in over 25 countries.
