OV2

OV2 5 [USAF]

The OV2 (Orbiting Vehicle 2) series satellites were originally built for project ARENTS (Advanced Research Environmental Test Satellite), which was intended to obtain supporting data for the Vela program. After the cancellation of the ARENTS program, the already built hardware was reused for OV2, a low-cost series of experimental satellites, which were to be launched for free on Titan-3C test flights to very different orbits. OV2 2 would have been launched to a circular 400 km orbit and OV2 4 would have been launched on an earth escape trajectory, but both were cancelled.

Payloads:

• OV2 1: Subliming solid motor, particle and fields detectors, plasma probes, magnetometers
• OV2 2: Optical sensors
• OV2 3: Solar experiments
• OV2 4: Optical measurements from a highly eccentric trans-lunar orbit
• OV2 5: 2 scintillation detectors, faraday cup, spherical ion trap, 2 electrostatic analysers, magnetometer, VLF receiver, ORBIS-High beacon, Lyman-alpha scanning UV photometer

OV2 2 and OV2 4 were cancelled, when the Titan-3C test program was changed.
