P17101: RIT-SPEX Gas Resistojet

Problem Definition

Table of Contents

Project Summary

The P17101 team will design and test an electrothermal propulsion system to meet the requirements of a hypothetical satellite mission designed by RIT Space Exploration (SPEX). SPEXsat, a geostationary communications satellite, requires a thruster to perform orbital station-keeping over a 10 year mission lifespan.

Team Vision for Problem Definition Phase

Use Cases

Satellites in Earth Orbit for long-duration missions in excess of 5-25 years encounter perturbations to their trajectories over time from residual atmospheric & orbital particles or variations in Earth's gravity. These spacecraft perform short maneuvers periodically to compensate for drift and orbital decay called "station keeping" maneuvers.
