Abstract
A system for generating a frequency hopping Global Positioning System (GPS) system includes: an on-orbit reprogrammable digital waveform generator (ORDWG) configured to generate a GPS signal comprising a resilient frequency-hopping spread spectrum GPS signal that hops at a hop rate between two or more GPS channels, the GPS signal further comprising a legacy direct-sequence spread spectrum signal for at least two of the two or more GPS channels; and a receiver configured to receive the GPS signal, the radio further configured to decode the GPS signal.
