Differential Correction Beacons • A GPS receiver is permanently fixed at a known benchmark • A correction factor that accounts for the differential between the actual and calculated position is continually broadcast on the FM radio band from the benchmark • In theory any errors generated by PDOP or atmospheric conditions can be eliminated by a GPS receiver that applies the correction factor • Multipath errors are not eliminated by differential beacons (DGPS)
GPS Accuracy & Precision • Precision is the reproducibility of the measurement • Accuracy is how close the measured position is to the actual location
