Subsystem Choices - GEO
Orbits and Trajectories
Subsystem choices depend on lots of intangibles such as the expertise and history that particular contractor may have with a particular subsystem choice. We'll look at a few choices here.
1. Discuss the pro's and con's of using lower power storage density with significant on-orbit heritage vs. batteries with higher power storage density but with less flight heritage.
2. Discuss the pro's and con's of relying on electric propulsion vs. chemical propulsion for stationkeeping.
