The Global Positioning System (GPS) provides extremely accurate position and timing information. A technique called Differential GPS (DGPS) is used to increase the accuracy of the GPS system. For the highest levels of performance, a technique known as Real-Time Kinematic (RTK) is used allowing one to two centimeters position accuracy.

The fundamental concept of DGPS/RTK is the use of a reference GPS receiver placed in a known location. The reference receiver monitors the system errors and formats corrections messages that are transmitted to the other GPS user equipment.

Pacific Crest Corporation manufactures a Positioning Data Link communication products that provide the critical connection between the GPS reference station and other GPS user equipment.
