11. The Structure of Exposures within Orbits with RPS2
Your Phase II Proposal and Using RPS2 . ... Perhaps the single most important thing to bear in mind when you look at your RPS2 output for a GHRS program is that RPS2 assumes your observations fall into tidy orbits with a nominal observing period and without being interrupted by the South Atlantic Anomaly (SAA). ... In some programs requiring very high wavelength precision you will not want to have your exposures interrupted by SAA passage or earth occultation because that time delay adds uncertainty. ...

13. Polar Orbiting Satellites
... Low Polar Orbit . ... Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. ... Many spacecraft use such orbits, e.g. the US Air Force surveillance satellites of the DMSP series, or the series of French Earth-resources spacecraft SPOT . ... If the satellite then starts near a noon-midnight orbit, it will always pass near noon and near midnight. ...
