Trimble R8 GPS Receiver Operation
This chapter introduces the Trimble R8 GPS receiver. This receiver is
designed for GPS surveying applications. The receiver incorporates a
GPS antenna, receiver, internal radio with a transmit option or an
internal GSM module, and battery in a rugged light-weight unit that is
ideally suited as an all-on-the-pole RTK rover. Three LEDs allow you to
monitor the satellite tracking, radio reception, data logging status, and
power. Bluetooth® wireless
technology provides cable-free
communications between receiver and controller. The Trimble R8
receiver provides 24 total channels of L1/L2 satellite tracking, and
supports logging of raw GPS observables to the handheld controller for

The receiver is available as a standalone rover, base station, or as part of
the GPS Total Station® system, offering maximum versatility in the
system configuration to meet your specific requirements.
