This home page provides access to data set
which includes the archived data from the Cylindrical
Electrostatic Probe (CEP) experiment on the ISIS-2 satellite.
ISIS-2 was launched on 1971-04-01 into a circular orbit at about
1400 km with an inclination of 88.1 degrees. It's payload
included sweep- and fixed-frequequency ionosondes, a VLF receiver,
energetic and soft particle detectors, an ion mass spectrometer,
an retarding potential analyzer, a radio beacon, a cosmic radio noise
experiment, photometers (3914, 5577, and 6300 Angstrom) and the CEP.
A tape recorder with 1-h capacity was included on the satellite.
Data were also collected during overflights of several telemetry
stations. The telemetry stations were in areas that provided
primary data coverage near the 80-deg-W meridian and in areas near
Hawaii, Singapore, Australia, the UK, Norway, India, Japan,
Antarctica, New Zealand, and Central Africa.
ASCII data set also contains needed spacecraft position data, IGRF model parameters, and indices.
