Definition Edit

Low-earth orbiting satellite(s) (LEOS) are "smaller and cheaper to design, build, and launch than traditional geosynchronous earth orbiting satellites (GEOS)."[1] They are placed in lower orbital positions (500 to 1,400 kilometers [310 to 870 miles]) than are GEOS. The lower orbital paths allow them to be operated with less power and reduce the time delays that plague communications (time delays limit the usefulness of GEOS communications for some time-sensitive applications) using GEOS, which orbit at distance up to 60 times greater than LEOS.

Overview Edit

Networks of these small satellites provide data ("little" LEOS) and voice ("big" LEOS) services to portable receivers all over the world.
