The chapter considers the current state of work on flight models of pulsed plasma propulsion systems. It is shown that the primary application area for propulsion systems based on an ablative pulsed plasma thruster is the station-keeping of small spacecraft with the power of supply system of up to 100 W and with an active lifetime in a range from 1 to 10 years in low Earth orbits with altitudes in a range from 400 to 700 km. It is also shown that ablative pulsed plasma thrusters can be efficiently used to solve the problems of accurate attitude control and angular stabilization of spacecraft.
