GNSS Receiver
6 items
- GNSS Frequency
- GPS: L1C/A, L2C, L5BDS: B1I, B2I, B3I, B1C, B2a, B2bGALILEO: E1, E5a, E5b, E6GLONASS: L1, L2QZSS: L1C/A, L2C, L5L-Band
- Accuracy in Base Station and Relay Station Mode
- Single Point Accuracy (Uncalibrated): Horizontal 1.5 m (RMS), Vertical 3.0 m (RMS)Satellite-Based Differential Accuracy: convergence time 20 mins, Horizontal 30 cm (RMS), Vertical 40 cm (RMS)Network RTK Calibration: Horizontal 1.0 cm (RMS) + 1 ppm, Vertical 3.0 cm (RMS) + 1 ppmBase station calibration coordinate accuracy depends on various factors. For surveying, high-precision flight paths, etc., it is recommended to calibrate during periods of inactive ionosphere, in open, unobstructed environments with no electromagnetic interference or multipath effects, using four or more GNSS systems.
- Accuracy in Rover Station Mode
- RTK Accuracy (Fixed Survey): Horizontal 0.8 cm (RMS) + 1 ppm, Vertical 1.5 cm (RMS) + 1 ppmRTK Accuracy (Tilt Survey): 0° to 60°, Horizontal 8 mm + 0.7 mm/° tilt (accuracy <2 cm within 30°)Measurement accuracy depends on various factors. This value is obtained under normal conditions with an unobstructed view, good satellite distribution, low ionospheric activity, and no electromagnetic interference or multipath effects.Intense vibrations and rapid rotations can affect the accuracy of the inertial measurement unit.
- Satellite-Based Precise Point Positioning
- Supported Frequencies: BDS B2b, GALILEO E6, L-BAND (L-band will be supported in later versions)Convergence Time: 20 minsHorizontal: 30 cm (RMS)Vertical: 40 cm (RMS)
- Differential Data Transmission Format
- When used as a base station or relay station, records RTCM 3.2 raw observation data in DAT format.In rover station mode or in calibration mode: supports RTCM v3.0, v3.1, v3.2, v3.3, MSM4, MSM5, MSM6, MSM7; receivers supporting four or more GNSS systems are recommended.
