NEO-F9P-15B | RTK Centimeter-level | Built-in Geomagnetic Field
Product Features
The Q43 NEO-F9P GNSS Helical RTK Module is an integrated RTK smart positioning antenna module based on the u-blox NEO-F9P-15B, integrating a high-precision RTK positioning engine, a helical antenna, and a geomagnetic sensor into a compact structure. The module supports multi-constellation, multi-frequency GNSS signal reception (GPS, BeiDou, GLONASS, Galileo, and QZSS), possessing dual-frequency RTK centimeter-level positioning capabilities. It provides stable and reliable high-precision positioning performance, suitable for applications such as intelligent robots, the sharing economy, precision agriculture, engineering surveying, handheld terminals, and vehicle navigation.
- Based on the u-blox NEO-F9P-15B high-precision positioning module, it supports dual-frequency RTK centimeter-level positioning.
- The RTK positioning engine and helical antenna are integrated into a single design, resulting in a compact structure, easy installation, and suitability for integration.
- Built-in three-axis geomagnetic sensor, suitable for compass, electronic compass and heading aid applications.
- Multi-satellite and multi-frequency support, including GPS, BeiDou (BDS), GLONASS, Galileo, and QZSS satellite systems.
- Supports A-GNSS assisted positioning, which can shorten the initial positioning time through auxiliary data.
- Supports enhanced systems such as WAAS, EGNOS, GAGAN, and QZSS SBAS.
- Supports u-center software configuration, facilitating the setting of output protocol, update rate, and RTK working mode, among other functions.
- Wide input voltage design, operating voltage range 3.3V ~ 16V, adaptable to various power supply environments.

RTK mobile station, RTK base station
Centimeter-level positioning
The two Q43 NEO-F9P GNSS Helical RTK Modules can be used as an RTK base station and a rover, respectively.
With known fixed ground coordinates, the Q43, set to base station mode, can build a continuously operating reference base station and output differential correction data. Alternatively, it can purchase and access RTK ground-based augmentation services to send differential correction data to the Q43 rover that uploads approximate location information via the network. The rover terminal can perform real-time calculations and converge quickly under error environments such as multipath, ionospheric and tropospheric refraction, achieving centimeter-level positioning within seconds.
Supports concurrent reception of multiple satellite systems
Supports multiple satellite systems including GPS, BeiDou (BDS), GLONASS, Galileo, and QZSS.
