Process ephemeris data.
Reformat the user specified ephemeris data and write it to a standard ephemeris data file. Equatorial crossing information can also be calculated and displayed.
- SATID
- Satellite number

- ORBIT
- Orbit number. The satellite orbit number (e.g., 12181)
- MEANAN
- Mean anomaly. Entering "21966907" signifies .21966907 revolutions.
- MEANMO
- Mean motion. Entering "82840512" signifies .82840512 radians/herg.
- ODECAY
- Orbital decay. Entering "00060" signifies .0006 1.E-5 radians/herg squared.
- ECCENT
- Eccentricity. Entering "00121013" signifies a value of .00121013
- ARGPER
- Argument of perigee. Entering "97265103" signifies a value of .97265103 revolutions.
- LONGASC
- Longitude of ascending node. Entering "59806393" signifies a value of .59806393 revolutions.
- INCLINE
- Inclination. Entering "27503749" signifies a value of .27503749 revolutions.
- EPDATE
- Date of epoch. Epoch is at 00:00:00 GMT. Enter using the format "YYMMDD".
- PRINT(--)
- Output destination. This output contains the equatorial crossing, the time of ascending node, and the orbit number for each of the orbits.
= --: No report. No equatorial crossing report will be generated. = TERM: Terminal. Output is sent to the user's terminal. = LP: Line printer. Output is sent to the printer defined by $PRINTER. = Filename: User-supplied filename. Output is sent to the user-supplied file with the extension .prt.
The above input parameters are used to update the ephemeris data file "16969.dat" in ADAPSTABLES. The equatorial crossing information will not be calculated.
The user-specified ephemeris information is formatted and written to a standard ephemeris data file. This data file is composed of ephemeris data records which are sixty-nine characters long. The name of the appropriate ephemeris data file consists of the satellite ID number with a ";dat" suffix, and resides in the ADAPSTABLES directory. If the information already exists within the appropriate file, the file will not be updated. Equatorial crossing information may be computed and printed to a device specified by the user.
A duplicate record was found in the ephemeris data file, the duplicate record is ignored.
A fatal error was encountered. A more descriptive message immediately precedes this message.
