    Overview Introduction This chapter describes the GPS 5100 receiver and gives an overview of GPS, DGPS, and related information. When used with a Real-Time Kinematic (RTK) base station, the GPS 5100 receiver provides RTK positioning for high-accuracy, centimeter-level applications. For physical specifications, see Appendix A, Specifications.

    To use the RTK method, you must first set up a base station. The base station uses a radio link to broadcast RTK corrections to one or more rover receivers. The GPS 5100 receiver is a rover receiver, so another compatible receiver, such as a Trimble MS750™...

  • Page 17: Differential Gps Positioning (Dgps)

    For more information about RTK positioning, go to the Trimble website at www.trimble.com/ Differential GPS positioning (DGPS) 26.2 For differential positioning, the GPS 5100 receiver uses corrections from WAAS/EGNOS satellites or from OmniSTAR VBS or HP satellites. These differential systems use special algorithms to provide differential corrections that allow the rover receiver to calculate its position more accurately.

  • Page 18: Subscription-Based Corrections

    Overview Subscription-based corrections The GPS 5100 receiver uses OmniSTAR HP or OmniSTAR VBS differential corrections in the same way that it uses WAAS/EGNOS corrections. OmniSTAR corrections are provided on a subscription basis. The corrections that are produced by OmniSTAR HP algorithms are more accurate than the corrections that are produced by OmniSTAR VBS algorithms.

  • Page 19: Sources Of Error In Gps Positioning
