/AWS1/CL_GSTEPHEMERISDATA

Ephemeris data.

CONSTRUCTOR

IMPORTING

Optional arguments:

io_tle TYPE REF TO /AWS1/CL_GSTTLEEPHEMERIS /AWS1/CL_GSTTLEEPHEMERIS

Two-line element set (TLE) ephemeris.

For more detail about providing Two-line element sets to AWS Ground Station, see the TLE section of the AWS Ground Station user guide.

io_oem TYPE REF TO /AWS1/CL_GSTOEMEPHEMERIS /AWS1/CL_GSTOEMEPHEMERIS

Ephemeris data in Orbit Ephemeris Message (OEM) format.

AWS Ground Station processes OEM ephemerides according to the CCSDS standard with some extra restrictions. OEM files should be in KVN format. For more detail about the OEM format that AWS Ground Station supports, see OEM ephemeris format in the AWS Ground Station user guide.

io_azel TYPE REF TO /AWS1/CL_GSTAZELEPHEMERIS /AWS1/CL_GSTAZELEPHEMERIS

Azimuth elevation ephemeris data.

Use this ephemeris type to provide pointing angles directly, rather than satellite orbital elements. Use this when you need precise antenna pointing but have imprecise or unknown satellite trajectory information.

The azimuth elevation data specifies the antenna pointing direction at specific times relative to a ground station location. AWS Ground Station uses 4th order Lagrange interpolation to compute pointing angles between the provided data points.

AWS Ground Station automatically filters interpolated pointing angles, including only those that are above the site mask elevation of the specified ground station.

For more detail about providing azimuth elevation ephemerides to AWS Ground Station, see the azimuth elevation ephemeris section of the AWS Ground Station User Guide.
