RTK Rover and RTK Base Station
Centimeter-Level Positioning
Two Q43 NEO-F9P GNSS Helical RTK Module units can be
configured separately as an RTK base station and an RTK rover
At a known surveyed reference point, the Q43 configured as an RTK base station can establish a continuously operating reference station and output differential correction data. Alternatively, users can subscribe to an RTK correction service, which provides differential correction data over the network to Q43 rover after receiving their approximate position information. The rover can perform real-time calculations and rapidly converge under error conditions such as multipath effects, ionospheric delay, and tropospheric refraction, achieving centimeter-level positioning within seconds.
Supports Concurrent Reception from Multiple-constellation Systems
Supports Multi-constellation systems, including GPS, BDS, GLONASS,
Galileo, and QZSS
Supports Multiple Satellite-Based Augmentation Systems (SBAS)
Using multiple satellite-based augmentation systems and real-time error correction, the module significantly improves positioning accuracy and reliability in challenging environments. It supports multiple SBAS services, including WAAS, EGNOS, GAGAN, and QZSS SBAS.
