Abstract:

For Timation satellites, the position of the antennae transmitting signals used for Doppler tracking differs from the satellites center of gravity. As satellite tracking improves and more precise applications are rendered to satellite work, this difference may be significant. This report describes a procedure for computing the difference between the inertial and electrical centers and for relating this difference to a geocentric coordinate system as a function of the satellites position and velocity.
