This home page provides access to data set
which includes the archived data from the Cylindrical
Electrostatic Probe (CEP) experiment on the ISIS-1 satellite.
ISIS-1 (ISIS-A) was launched on 1969-01-30 into an elliptical orbit
(500-3500km) with an inclination of 88.4 degrees. It's payload
included sweep- and fixed-frequequency ionosondes, a VLF receiver,
energetic and soft particle detectors, an ion mass spectrometer,
an electrostatic analyzer, a beacon transmitter, a cosmic noise
experiment and the CEP. A tape recorder with 1-h capacity was
included on the satellite. The 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.
