SparkFun Electronics launches GNSS RTK module for positioning accuracy

SparkFun Electronics has introduced the SparkFun Quadband GNSS RTK Breakout (Qwiic), which is designed to improve positioning accuracy using the Quectel GNSS module. This module has a compact design and compatibility with the Qwiic connector, making it easy to integrate into various projects. Additionally, it shares the same dimensions, pin layout and connectors as the SparkFun GPS-RTK-SMA Breakout – ZED-F9P, offering a seamless upgrade path for users.

The LG290P module is a quad-band, multi-constellation, high-precision real-time kinematics (RTK) GNSS receiver capable of receiving signals from multiple frequency bands: L1, L2, L5 and L6/E6. It supports all GNSS constellations and offers support for Satellite Based Augmentation Systems (SBAS) — such as Wide Area Augmentation System (WASS) and European Geostationary Navigation Overlay Service (EGNOS) — as well as precise point positioning (PPP) services, including BDS PPP-B2b and MADOCA-PPP. The module is designed to provide precise navigation with fast convergence times and reliable performance through RTCM and RTK corrections.

The module features a built-in NIC anti-jamming unit, which uses advanced algorithms to detect and eliminate interference signals. This can significantly enhance signal reception in challenging electromagnetic environments. The device can be used in complex scenarios, such as urban settings or areas with dense tree cover. Due to its high precision and low power consumption, the SparkFun Quadband GNSS RTK Breakout – LG290P is ideal for applications in intelligent robotics, UAVs, precision agriculture, mining, surveying and autonomous navigation.
