1-Hour ISEE 3 Ephemeris Selected from Data Pool, in ASCII, Compressed


Availability: At NSSDC, Ready for Electronic Access

Time span: 1978-08-13 to 1987-02-07


This data set was generated at NSSDC by selecting data parameters from the ISEE 3 data pool tape, converting to ASCII, and compressing by gzip. The time resolution is about an hour and 4 minutes. Data records that contained fill data for the spacecraft position were not included in this data set. The data items, in order, are: year, day of year, bit rate code, maneuver code, spin period average (in seconds) over the hour, and the GSE X,Y,Z components of the spacecraft position (in km). The bit rate code is 1,2, or 4 for bit rates of 512, 1024, or 4028 bps, respectively. The maneuver code is 0 if there were no maneuvers during that time period (which can be up to an hour starting at the given time), and is 7 if there were any maneuvers during that time. Record length is 78 bytes.

The data are available on-line at: under directory /hourly_magnetospheric/
