S.7 Characteristics of <strong>Spacecraft</strong> <strong>Propulsion</strong> <strong>Systems</strong><br />
In order <strong>to</strong> fulfill attitude and orbit operational requirements of spacecraft, spacecraft<br />
propulsion systems are characterized in particular by:<br />
Very high velocity increment capability (many km/s)<br />
Low thrust levels (1 mN <strong>to</strong> 500 N) with low acceleration levels<br />
Continuous operation mode for orbit control<br />
Pulsed operation mode for attitude control<br />
Predictable, accurate and repeatable performance (impulse bits)<br />
Reliable, leak-free long time operation (s<strong>to</strong>rable propellants)<br />
Minimum and predictable thrust exhaust impingement effects
