OCTAHEDRAL RESEARCH SATELLITE MARK III; OV5-1 (ERS 27).
Abstract
The Octahedral Research Satellite - Mark III, ERS 27 (Air Force designation OV5-1) was launched into an eccentric earth orbit on 28 April 1967, and assigned international designation 1967-40E. The satellite was instrumented with a scientific payload and support subsystems designed to monitor soft X-rays, bremsstrahlung, and protons from solar active regions. The spacecraft was a regular octahedron with 11.5 inch edge length, weighing 16.3 pounds. It was designed to be spin stabilized at a rate of 12 RPM, and produce an average sunlit power of 4.0 watts. The scientific payload consisted of eleven radiation detectors and a sun aspect sensor. The payload data was sampled by a twenty-three segment commutator, processed by an IRIG 5 subcarrier oscillator, and transmitted in real time to the ground stations via a PAM/FM/PM 136MHz transmitter operating at 1 watt.
