    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)
    This one explains more about geo-transfer orbits. Actually goes into polar
    orbits as well.
    These above are both NASA sponsored sites.
    There is also some really good information at
    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
    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.

    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?
    Thank you,
