Abstract
A global positioning system comprises an RF receiver for receiving L.sub.1, L.sub.2 p-code or ca code modulated frequency outputs from one or more space vehicles, a multiplexer operably connected to the receiver multiplexes the L.sub.1 and L.sub.2 signals to the receiver, and code and carrier tracking loops operably connected to the receiver, each loop including a plurality of filters, one for tracking line-of-sight dynamics and another for determining ionosphere effects on the L.sub.1 and/or L.sub.2 signals.
