Current GPS equipment is small and reasonably priced and is finding its way into new applications every day. However, GPS does contain both Systematic and Random errors. Early use of this DGPS technique utilized UHF radios to send the corrections to nearby users. Today, OmniSTAR continuously monitors the signals of all GPs satellites at over 70 known locations around the world, eleven of which are in North America. The correction data is in a standard format called RTCM-104 that is recognized by virtually every GPs receiver.
