Introduction

• Horizontal: 3 mm (0.009 ft) + 0.5 ppm

• Vertical: 5 mm (0.016 ft) + 0.5 ppm

High-Precision Static (6)

• Horizontal: 3 mm (0.009 ft) + 0.1 ppm

• Vertical: 3.5 mm (0.011 ft) + 0.4 ppm

Post-Processed Kinematic

• Horizontal: 10 mm (0.033 ft) + 1.0 ppm

Data Logging

Characteristics

Recording Interval:

• 0.05 to 999 seconds

Physical

Characteristics

• Size: 22.8 x 18.8 x 8.4 cm (9 x 7.4 x 3.3 “)

• Weight: 1.4 kg (3.1 lb)

User Interface • Graphic OLED display

I/O Interface • RS232, RS422, USB, Bluetooth

• 1PPS output

Memory • 128-MByte internal memory (expandable through USB)

• Up to 400 hours of 15-s GNSS raw data from 18 satellites

Operation • RTK rover/base, post-processing

• RTK network rover: VRS, FKP, MAC

• Point-to-Point through Real-time Data Server (RTDS)

Software

•RTC Bridge

• NTRIP protocol

• Rover can decode RTCM messages 1021, 1022, 1023

and 1025 so that its position may be computed in the

same local coordinate system (and same local projection

with message 1025) as the one used at the base station.

4.Accuracy and TTFF specifications may be affected by atmospheric conditions, signal multipath, satellite

geometry and corrections availability and quality. Position accuracy specifications are for horizontal

positioning. Vertical error is typically less than twice the horizontal error.

5.Performance values assume minimum of five satellites, following the procedures recommended in the

product manual. High multipath areas, high PDOP values and periods of severe atmospheric conditions may

degrade performance.

6.Long baselines, long occupations, precise ephemeris used.
