Quectel LG290P quad-band GNSS module

Quectel Wireless Solutions’ LG290P quad-band GNSS module is designed to deliver high performance for demanding applications, enabling good RTK availability and quality even in challenging environments. Futureproofing applications by supporting constellations including GPS, GLONASS, Galileo, BDS, NavIC and QZSS, as well as SBAS support (WASS, EGNOS, MSAS and GAGAN) and satellite-based signals such as PPP-B2b, CLAS (QZSS L6) and Galileo HAS E6, the industrial-grade module receives the L1, L2, L5 and E6 frequency bands.

Designed to provide instantaneous centimetre-level accuracy, the module is compatible with Quectel triple band RTK services and offers coverage that supports base stations from long distances, enabling stable and high performance in difficult urban environments. This makes it especially suitable for sectors such as autonomous lawnmowers, delivery robots, surveying and precision agriculture.

According to the company, the quad-band module can enhance the RTK fix rate by 50% compared to dual band in extremely 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 a dual band solution.

The module supports a multi-frequency RTK algorithm, for rapid RTK positioning results even in challenging conditions such as under dense tree cover, alongside buildings or inside urban canyons. With anti-interference technology, it incorporates a professional-grade interference signal detection and narrowband interference cancellation, enhancing signal reception performance in complex electromagnetic environments. Moreover, supporting integrity monitoring and authentication information verification, the product aids automatic navigation systems in making control decisions, particularly fitting for critical applications like autonomous vehicles and lawnmowers.

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