Thruster-Based Attitude and Translation Control with Minimum Pulse-Count Disturbance Rejection

Thruster-based control typically requires a substantial engineering effort in order to mitigate an important issue: the control system tends to use many thruster pulses to accomplish what a single thruster pulse could do instead. This fundamental...

Model-Based Monitoring for Spacecraft Thruster Leakage

A report describes a method of detecting leakage in one of the 16 thrusters of the Cassini spacecraft. The detection method, implemented as part of the spacecraft flight software, is based on the fact that the three-axis rotational motion of a spacecraft is governed by the Euler's equation....

Performance of an Arc-Jet Thruster

A report discusses the design and testing of a laboratory-model arc-jet thruster designed to operate at a nominal power level of 300 W. This thruster is an intermediate product of continuing efforts to develop smaller, lower-power, higher-specific-impulse thrusters for use in a forthcoming generation of small...
