OV5 (ERS)

OV5 4 [USAF]

OV5 (Orbiting Vehicle 5) was a series of standardized, simple experimental satellites based on earlier ERS satellites. Each carried different experiments

OV5 1: Beryllium-window proportinal counter, solid state detectors, photomultipliers, 6 directional Geiger-counters
OV5 2: Omnidirectional spectrometers, Geiger counters, directional proton and electron detectors
OV5 3: Friction tests (wipers and material samples)
OV5 4: Boiling fluids experiment
OV5 5: Boom mounted magnetometer, 7 particle detectors, LVF receiver
OV5 6: Solid state detectors, Faraday cup, magnetic spectrometer, fluxgate magnetometer
OV5 7: Solar X-ray detectors
OV5 8: Vacuum friction experiments
OV5 9: VLF receiver, solar X-ray detector, 4 particle detectors

OV5 7 lost its launch slot on OV1 17 for a relaunch of Orbiscal and was never launched
