Algorithms were developed for use in computer programs for determination attitude and orbit control thruster performance for satellites under control of the European Space Operations Center. The impact of parameters such as temperature, pressure and aging on thruster behavior in pulsed as well as in continuous burn mode are analyzed. From analysis of ground tests results, some mathematical model structures are proposed, concerning mainly the pulse shape and its integrated effect on the spacecraft (impulse bit). Analysis of satellite flight sequences, in spin and in 3 axes stabilized cases lead to a selection of four particular maneuvers for which data transmitted through telemetry allows identification algorithms to be applied. These include nutation motion, wheel unloading, spin axis reorientation and north-south station keeping.
