Positioning Data Links For Land Surveying 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.

Wireless Data Link for Machine Control Applications

Sitecom is a rugged, reliable radio modem that enables high-precision GPS locating and tracking-machine control-for bulldozers, tractors, and other high-value assets used in construction, agriculture, and other applications.

The Sitecom radio incorporates unique features to ensure reliable and cost-effective operation in tough outdoor machine control environments. For example, a specially designed mounting bracket isolates the unit from vibration and shock that could degrade its performance. Sitecom is engineered to mount on or in the vehicle; a TNC rubber duck antenna that mounts easily to the radio simplifies installation and provides rugged reliability.

As a member of Pacific Crest's field-proven Positioning Data Link (PDL) family, Sitecom is compatible with and supports all major GPS manufacturers worldwide. To purchase complete PDL Kits go to our dealer locator to find a dealer close to you.
