Here are couple of web sites that talk about transfer orbits. They can explain it a lot better than I can. This one talks about transfer orbits in general (such as the inter-planetary transfer orbits) http://www.jpl.nasa.gov/basics/bsf4-1.html This one explains more about geo-transfer orbits. Actually goes into polar orbits as well. http://www.jpl.nasa.gov/basics/bsf5-1.html These above are both NASA sponsored sites. There is also some really good information at http://www.ee.surrey.ac.uk/Personal/L.Wood/software/SaVi/ on the various types of orbits. In fact this whole site is an excellent resource for those who are interested in satellites in general. AMSAT-NA also has some pretty good info on their birds and what they are up to. www.amsat.org If this doesn't satisfy your thirst for info, go to one of the super search engines (such as www.dogpile.com) and start hunting. Or you could lay out the cash and get some books on orbital mechanics. All for now Lloyd There is another somewhat commonly used orbit called a And actually all of the satellites do this or some other similar maneuver using a transfer orbit. It is a LOT more economical to use gravity to swing it up there vs. using fuel and powering yourself all the way. ----- Original Message ----- From: "Mitchell" <escape@velocity.net> To: "SeeSat" <SeeSat-L@satobs.org> Cc: <lloyd.thomson@osss.com> Sent: Thursday, October 11, 2001 5:12 PM Subject: GEO orbit > To reach GEO, lots of them > will go into what they call a transfer orbit, and then maneuver out of that > one into their assigned location. Lloyd, At the risk of boring everyone to tears, could you please explain to me what's involved in getting a GEO into it's orbit?
