[edit] Remaining problems with the article

  • Not 90 degrees relative to the viewpoint of someone standing on the planet's equator!
  • Not a different longitude everytime necessarily. A satellite with the same orbital period as the rotational period of the planet will pass over the same spot every time. And an integer multiple of the period...

  • AND the longitude of the satellite precesses (sp) during every orbit. So the longitude is not the same suring one orbit nevermind two successive.

[edit] Cost, launch site?

I assume it costs more to get something in a polar orbit since you don't have the earth's rotation helping you out. Also, shouldn't the ideal launch site be on one of the poles? If so, where do polar orbits get launched from? —Ben FrantzDale 05:15, 15 March 2007 (UTC)


[edit] There is no disadvatage if multiple satellites (constellation) are used in a polar obit configuration

Satellite phone providers such as Iridium, are able to provide phone access globally anywhere on land, or at sea using their constellation of 66 satellites in a polar orbit configuration, at an altitude of 780 kilometers (485 miles). —Preceding unsigned comment added by Tjmartinez (talk • contribs) 18:29, 19 September 2007 (UTC)
