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 circuitry in the Trimble R8 Model 4 GNSS receiver provides up to 440 channels for satellite tracking, and supports logging raw GNSS observables to the internal receiver memory or to a handheld controller for post processed applications. The receiver is available as a standalone rover, base station, or as part of the GNSS Total Station® system, offering maximum versatility in the system configuration to meet your specific requirements. The receivers provide the following features: Future-proof Trimble 360 technology (Trimble R8 Model 4), which includes advanced Trimble Maxwell 6 Custom Survey GNSS chips with 440 channels and allows the receiver to track the following: GPS: L1 C/A, L1C, L2C, L2E, L5 GLONASS: L1 C/A, L1P, L2 C/A, L2P, L3 Galileo: E1, E5A, E5B BeiDou (COMPASS): B1, B2 SBAS: QZSS, WAAS, EGNOS, GAGAS Centimeter-accuracy, real-time positioning with RTK/OTF data, up to 20 Hz position updates (R8 Model 4) or up to 10 Hz (R6 Model 4 and R4 Model 3) Submeter-accuracy, real-time positioning using pseudorange corrections Automatic OTF (on-the-fly) initialization while moving Single Lithium-ion rechargeable battery Cable-free Bluetooth communications with Trimble controllers Two RS-232 serial ports for: Trimble Format (CMR, CMR+™ and CMRx) input and output RTCM SC-104 input and output (RTCM 2.1, 2.3, 3.0, 3.1) 23 NMEA outputs GSOF, RT17, and RT27 outputs Supports BINEX and smoothed carrier One TNC radio antenna connector Internal memory for data storage Specifications: Feature Specification Size 19.0 cm (7.5") wide x 10.4 cm (4.1") deep including connectors Weight: with internal battery, radio, and standard antenna 1.52 kg (3.35 lbs) Operating times on internal 2.6 Ah battery (varies with temperature) 450 MHZ receive only - 5 hours 450 MHz receive/transmit: 2.5 hours (varies with wireless data rate) GSM: 4.7 hours Power input 11–28 V DC with over-voltage protection on port 1 (7-pin lemo) Operating temperature –40 °C to +65 °C (–40 °F to +149 °F) Storage temperature –40 °C to +75 °C (–40 °F to +167 °F) Humidity 100% condensing, unit fully sealed Casing Water/dustproof IP67 dustproof, protected from temporary immersion to depth of 1 m (3.28 ft) Positioning specifications Feature Specification Positioning performance Code differential GNSS positioning Horizontal: 0.25 m + 1ppm RMS Vertical: 0.50 m + 1ppm RMS SBAS differential positioning accuracy: typically <5 m 3DRMS Static GNSS surveying High-precision static Horizontal 3 mm + 0.1 ppm RMS Vertical 3.5 mm + 0.4 ppm RMS Static and FastStatic Horizontal 3 mm + 0.5 ppm RMS Vertical 5 mm + 0.5 ppm RMS Kinematic surveying Postprocessed Kinematic (PPK) GNSS surveying Horizontal 8 mm + 1 ppm RMS Vertical 15 mm + 1 ppm RMS Real-Time Kinematic Surveying Horizontal 8 mm + 1 ppm RMS Vertical 15 mm + 1 ppm RMS Network RTK Horizontal 8 mm + 0.5 ppm RMS Vertical 15 mm + 0.5 ppm RMS Initialization time typically < 8 seconds Initialization reliability typically > 99.9% Technical specifications Tracking: Trimble R8 Model 4 GNSS receiver Advanced Trimble Maxwell 6 Custom Survey GNSS chips with 440 channels.
