The attitude and orbit control algorithm for the upper stage of a multiple payload launcher is described. The mission of the launcher is to put several payloads into an orbit. The payload may be released in a three axis stabilized or spinning mode. The unknown dispersions (dynamic unbalance and thrust level) and the changing configuration during the sequence requires novel features in the control algorithm: the estimation of the dynamic unbalance after each release, a special filter for the accelerometer output, and gain scheduling of the observer and filter gains.
