A Low Earth Orbiting (LEO) satellite is used for broadcasting differential navigation corrections. Using LEO satellites, the "footprint" of the beam is much smaller than for geosynchronous satellites, and therefore data link bandwidth requirements are reduced to sufficiently cover an entire area. With a LEO satellite transmitting in multiple beams, these footprints become even smaller. Corrections targeted to such a small area could have the form of local area corrections (for example, raw measurements taken from a navigation reference station) using the LEO satellites.
