transfer orbit stage
1Transfer orbit stage — The Transfer Orbit Stage (TOS) was an upper stage rocket developed by Martin Marietta on a subcontract to Orbital Sciences Corporation during the late 1980s and early 1990s. Orbital Sciences was the prime contractor for NASA for TOS. TOS was… …
2Geostationary transfer orbit — A Geosynchronous Transfer Orbit or Geostationary Transfer Orbit (GTO) is a Hohmann transfer orbit around the Earth between a low Earth orbit (LEO) and a geosynchronous orbit (GEO). It is an ellipse where the perigee is a point on a LEO and the… …
3Parking orbit — A parking orbit is a temporary orbit used during the launch of a satellite or other space probe. A launch vehicle boosts into the parking orbit, then coasts for a while, then fires again to enter the final desired trajectory. The alternative to a …
4Inertial Upper Stage — The Inertial Upper Stage or IUS is a two stage solid fueled booster rocket developed by NASA and the U.S. Air Force for the launching of large payloads from either a Titan III (later Titan IV) rocket or from the payload bay of the Space… …
