Appendix E -- Test Case Results Listing

Source

AIAA 2006-6753-Rev1 — Pages 37—46

TCPPVER.OUT

The results are given below for the verification TLE data in Appendix D. Note that this version includes the results of the Lyddane choice using the perturbed inclination as indicated in the GSFC code, and also uses the WGS-72 constants. There is also a “true” time reference at the end of each line to facilitate the conversion with minutes from epoch and UTC. The coordinate system should be considered as TEME of date. The only difference from the original paper is satellite 23599 which had small changes as a result of the consistency with AFSPC option. The dates are adjusted for the leap second for satellite 20413, but this was done outside the SGP4 routine. These test case results were run using the ‘a’ option to best emulate AFSPC operation.

Column Format

Each row contains:

Column	Description
Min from epoch	TSINCE value in minutes
position x km	X component of position vector (TEME)
position y km	Y component of position vector (TEME)
position z km	Z component of position vector (TEME)
vel km/s	X component of velocity vector (TEME)
vel km/s	Y component of velocity vector (TEME)
vel km/s	Z component of velocity vector (TEME)
year mon day hr min sec	UTC time reference

Notes

• All positions are in kilometers, all velocities in km/s.
• Coordinate frame is TEME of date.
• WGS-72 gravitational constants are used.
• The Lyddane choice uses the perturbed inclination as in the GSFC code.
• Results were generated using the ‘a’ option to best emulate AFSPC operation.
• Satellite 23599 had small changes from the original paper as a result of consistency with the AFSPC option.
• Dates for satellite 20413 are adjusted for the leap second, done outside the SGP4 routine.
• The complete machine-readable dataset with all digits preserved is in ../data/test_cases.json.
