Parameter descriptions

Output: Orbit Layer: Output orbit segment

Specifies the orbit segment (type 16) to which orbit information will be added. If this parameter is not specified, a new orbit segment is created. If specified, this value must be greater than zero.

Orbit Information File

Specifies the name of the input text file from which to read the orbit information.

Note: If you input the FULL format text file (from ORBITWR function, RTYP parameter), the per-scanline data will not be read; the scanline data values will be defaulted to zero. See ORBITWR for more information.

Orbit Layer Name

Specifies a name (up to 8 characters) identifying the output orbit segment. This string is displayed by ASL and may be changed with MAS.

This parameter is used only if a new segment is created. The default segment name is "ORBIT".

Orbit Layer Description

Describes (in up to 64 characters) the contents or origins of the output orbit segment. This string is displayed with ASL and may be changed with MAS.

This parameter is used only if a new segment is created. The default value is "Orbital Ephemeris Data".

Details

ORBITRD reads orbit information from a text file (TFILE). It then writes it to an output orbit segment (ORBIT) in the output file (FILE).

If the ORBIT segment (type 160) is specified, the orbit information in the text file updates the existing orbit segment. If ORBIT is not specified, a new orbit segment (type 160) is created.

DBSN (Orbit Layer Name) and DBSD (Orbit Layer Description) define the name and description of the output orbit segment, respectively.
