These motors are used as apogee or perigee motors depending on their performance inaccordance with the combined (satellite–motor) mass and the velocity increment to be impartedto it. Note that the large acceleration (tens of g) due to the quick burning of a large amount ofpropellant generating very high thrust (tens of kN) induces significant mechanical stresses on thesatellite, in particular if the satellite is of a large size with many appendices.
