Introduction All differential beacon receivers decode correction data determined at the beacon transmitter site via a GPS Cautions receiver(s). The GPS system is operated by the govern- ment of the United States which is solely responsible for their accuracy and maintenance. The DGPS beacon transmitters are operated by the U.S. Coast Guard (or similar government agency in other countries) which is responsible for their accuracy and maintenance.

Operation First Time Fix Using the Once the DGPS is installed and powered on, it will DGPS 53 begin to search for satellites and a DGPS beacon signal. Initially, it may take longer than normal to scan through the DGPS beacon frequencies. The DGPS 53 will output corrected navigation data once it has calculated an initial position fix and sucessfully received a DGPS signal. The following data will be output in NMEA 0183, Version 2.0 format: • Latitude/Longitude/Altitude • Velocity • Date/Time • Er

Operation Using the DGPS 53 Sensor Initialization Information (PGRMI) The $PGRMI sentence provides information used to initialize the position and time used for satellite acquisition. Receipt of this sentence by the DGPS 53 causes the software to restart the satellite acquisition process. If there are no errors in the sentence, it will be echoed upon receipt. If an error is detected, the echoed PGRMI sentence will contain the current default values. Current PGRMI defaults can also be obtained by
