Subject: A new model for GPS BlockIIR solar radiation pressure
Dear Colleagues,
I was recently able to test a new solar radiation pressure model for GPS
Block IIR satellites. This model was designed by the manufecturer of
the spacecraft, Lockheed-Martin, and is in the form of a table. Its main
advantage over the T30 model is in the modeling of the solar pressure during
the fixed yaw regime and in modeling Y axis forces. My tests of this model
focused on identifying any major inconsistencies or problems with this model.
Failing to find these, I can recommend this model for more thorough testing.
The model is free for anyone's use but with out any liability implied.
I placed the table on our ftp server "sideshow", directory
"pub/GPS_yaw_attitude" in the file BlockIIR_srp_table. Explanations are
included in the file.
For more information about GPS Block IIR solar pressure and attitude
models consult IGS mail #1653 from July 30, 1997.
Sincerely,
Yoaz Bar-Sever
