LG290P (03) GNSS Module

Quectel LG290P (03) is a quad-band, multi-constellation, high-precision GNSS module that supports simultaneous reception of GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations, as well as SBAS augmentation systems (WAAS, EGNOS, BDSBAS, MSAS, GAGAN, and SDCM). It also supports precise point positioning services like PPP-B2b and PPP-HAS. A built-in professional-grade interference detection and cancellation algorithm effectively mitigates multiple narrowband interferences. This significantly enhances signal reception performance, particularly in complex electromagnetic environments. Furthermore, LG290P (03) supports multi-constellation, quad-band RTK algorithms, ensuring fast and reliable high-precision positioning even in challenging environments such as urban canyons and dense foliage. It also features an RTKHOLD function that leverages observation data model prediction technology to maintain high-precision positioning for up to 10 minutes during unexpected RTK differential service interruptions.

The LG290P (03) supports integrity information detection functions, such as protection levels, that assist control decision-making for applications like automated navigation. It also supports on-chip memory ECC (error correction code) verification and a secure boot mode, providing additional protection for firmware security. Additionally, the module offers rich peripheral interfaces, including UART and I²C, to meet diverse user application requirements. Its advantages include high precision and low power consumption.
