OV5 4 [USAF]
OV5 (Orbiting Vehicle 5) was a series of standardized, simple experimental satellites based on earlier ERS (ORS Mk.3) satellites. Each carried different experiments:
- OV5 1 (ERS 27): Beryllium-window proportinal counter, solid state detectors, photomultipliers, 6 directional Geiger-counters
- OV5 2 (ERS 21): Omnidirectional spectrometers, Geiger counters, directional proton and electron detectors
- OV5 3 (ERS 20): Friction tests (wipers and material samples)
- OV5 4 (ERS 28): Boiling fluids experiment
- OV5 5 (ERS 29): Boom mounted magnetometer, 7 particle detectors, LVF receiver
- OV5 6 (ERS 26): Solid state detectors, Faraday cup, magnetic spectrometer, fluxgate magnetometer
- OV5 7 (ERS 22): Solar X-ray detectors
- OV5 8 (ERS 19): 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.
OV5 9 featured a modified structure with a 7 cm girth band stretch.
