Overview
Quectel LG290P series is a quad-band, multi-constellation high-precision GNSS module series, which 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.
The LG290P series integrates professional-grade interference detection and cancellation algorithm to effectively mitigate multiple narrow-band interferences, significantly enhancing signal reception performance, particularly in complex electromagnetic environments. Furthermore, it supports multi-constellation, quad-band RTK algorithms, ensuring fast and reliable high-precision positioning even in challenging environments like urban canyons and under dense foliage. Notably, the series features the RTK HOLD function, which leverages observation data model prediction technology to maintain high precision positioning for up to 10 minutes during unexpected RTK differential service interruptions.
The LG290P series supports integrity information detection functions, such as protection levels, which can assist in control decision-making for applications like automated navigation. Firmware security is fortified via on-chip memory ECC (Error Correction Code) verification and the Secure Boot mode. Additionally, the module offers extensive peripheral interfaces, including UART and I2C*, to meet diverse user application requirements.
With its high precision and low power consumption, the LG290P series is an ideal choice for high-precision navigation applications such as intelligent robots, precision agriculture, mining, surveying and mapping, lawn mower and autonomous driving.
