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.
