2.1 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.
2.2 Standard Features of the GPS 5100 Receiver
A standard GPS 5100 receiver provides the following features:
• 12 GPS (C/A-code) tracking channels, code carrier channels
• Horizontal RTK positioning accuracy 2.5 cm (0.98 in) + 2 ppm,
2 sigma; vertical RTK positioning accuracy 3.7 cm (1.46 in)
+2ppm,2sigma
• Submeter differential accuracy (RMS), assuming at least five
satellites and a PDOP of less than four
• Combined GPS/DGPS receiver and antenna
• System level cable
•AgRemote utility with four-button keypad to configure and view
system properties (download from the Ag Leader website at
www.agleader.com)
• LED status indicator
• The receiver outputs a 1 PPS (pulse per second) strobe signal on
both ports. This signal enables an external instrument to
synchronize its internal time with a time derived from the very
accurate GPS system time.
• WAAS differential correction compatibility
• Field computer compatibility
• EVEREST™ multipath rejection technology
• OmniSTAR VBS and HP positioning compatibility
