Quectel LG290P is a quad-band, multi-constellation high-precision GNSS module, which supports simultaneous reception of GPS, GLONASS, Galileo, BDS, QZSS and NavIC constellations, as well as SBAS augmentation systems (WASS, EGNOS, BDSBAS, MSAS, GAGAN and SDCM). The module supports Quad-band RTK with fast convergence time and reliable performance.

An integrated professional-grade interference signal detection and elimination algorithms effectively mitigates against multiple narrow-band interference sources which significantly improves signal reception performance, particularly in complex electromagnetic environments. The LG290P module supports multi-mode and Quadband RTK algorithm solutions, ensuring fast and reliable high-precision RTK positioning in complex scenarios such as urban environments and deep tree cover.

LG290P supports protection-level and other integrity detection information, aiding control decisions in automatic navigation application scenarios. With on-chip storage ECC verification and Secure Boot safe loading mode, the module protects the operating firmware safety. The LG290P accommodates users diverse needs with a choice of interfaces including UART, SPI and I2C.
