Quectel LG290P quad-band GNSS module

Quectel Wireless Solutions has launched the LG290P quad-band GNSS module, designed to deliver high performance for demanding applications. The GNSS module also enables RTK availability and quality in challenging environments. Designed to provide the centimetre-level accuracy needed for applications such as precision agriculture, robotic lawnmowers, surveying and personal robots, the module also delivers coverage that supports base stations from long distances.

Futureproofing applications by supporting constellations including GPS, GLONASS, Galileo, BDS, NavIC and QZSS, as well as SBAS support (WASS, EGNOS, MSAS and GAGAN) and advanced satellite-based signals such as PPP-B2b, CLAS (QZSS L6) and Galileo HAS E6, the device is an industrial-grade module that receives L1, L2, L5 and E6 frequency bands.

The GNSS module is also compatible with Quectel triple band RTK Services. The quad-band solution can enhance the RTK fix rate by 50% compared to dual band in challenging environments, such as a garden encircled by trees and walls. Additionally, it can reduce the time to achieve RTK fix to less than 5 s, in contrast to the 10–15 s required by the dual band solution.

The module supports an advanced multi-frequency RTK algorithm, to facilitate rapid RTK high-precision positioning results in conditions such as under dense tree cover, alongside buildings or inside urban canyons. With anti-interference technology, the module incorporates a professional-grade interference signal detection and Narrowband Interference Canceller (NIC), thereby enhancing signal reception performance in complex electromagnetic environments.

The module also incorporates an on-chip ECC check and Secure Boot for firmware protection. Measuring 12.2 x 16 x 2.6 mm, it offers design flexibility for customers, reducing integration challenges and enabling compact designs for a range of precision products. Customers are also able to streamline their design process by sourcing the appropriate antenna for the module, thereby enabling flexibility and compatibility for diverse project requirements.
