GNSS-RTK High Precision Positioning Kit with LoRa (EU 868 MHz, GPS / GLONASS / Galileo / BDS / QZSS)

The LoRa-Based GNSS-RTK High Precision Positioning Kit (EU Version) is a complete, out-of-the-box solution designed to deliver centimeter-level positioning accuracy. By leveraging Real-Time Kinematic (RTK) technology, the system utilizes a stationary base station to transmit real-time correction data via a LoRa wireless link, operating on the EU 868 MHz frequency, to a mobile rover unit. This process corrects for atmospheric and satellite orbit errors, enabling a positioning precision of up to 5cm + 1ppm. The key advantages of this kit are its exceptional accuracy, pre-configured simplicity, reliable long-range data transmission, and robust multi-constellation support, tracking signals from GPS, GLONASS, Galileo, BDS, and QZSS. It is engineered for applications demanding high precision, such as autonomous vehicle navigation, land surveying, and asset tracking.

Centimeter-Level RTK Accuracy

At the core of the kit are the Quectel LC29H series modules, which enable the system to achieve an RTK Fixed positioning status. This represents the highest level of precision, far surpassing the meter-level accuracy of standard GPS or GNSS receivers. By processing carrier phase observations and applying differential corrections, the mobile unit can determine its position with remarkable repeatability and reliability, making it suitable for professional and mission-critical tasks.

Out-of-the-Box Simplicity

This kit is engineered to make advanced RTK technology accessible. Unlike traditional component-based solutions that require users to configure their own data links, this system comes with a pre-configured wireless connection between the base station and the mobile unit. As a fully integrated solution, it eliminates complex setup procedures, significantly lowering the barrier to entry for developers, makers, and students, and allowing for rapid deployment in the field.

Reliable Long-Range Wireless Link

The transmission of correction data is handled by an integrated LoRa communication system operating at 868MHz. This technology provides a stable and reliable data link with a range of up to 1.5 kilometers in open areas. The robust wireless connection ensures that the mobile unit consistently receives the necessary RTCM data from the base station, maintaining high-precision positioning even at a distance.

Advanced Dual-Band, Multi-Constellation Support

To ensure optimal performance and signal availability, the modules support dual-band (L1/L5) reception across multiple global satellite navigation systems, including GPS, GLONASS, Galileo, BDS, and QZSS. This multi-constellation capability allows the receiver to track more satellites simultaneously, leading to faster signal acquisition, quicker convergence times (under 10 seconds), and improved positioning robustness in challenging environments such as urban canyons or areas with partial sky obstruction.
