Quectel LG580P
High-Precision GNSS Module
  • Multi-band, multi-constellation high precision GNSS module
  • 21.0mm × 16.0mm × 2.6mm
  • Operating temperature: -40°C to +85°C
  • Tracking sensitivity: -160 dBm
  • RoHS compliant

LG580P (03) is a full-constellation, multi-band GNSS module with 1040 tracking channels, which supports concurrent reception of GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations, as well as multiple SBAS systems (WAAS, EGNOS, BDSBAS, MSAS, GAGAN, KASS, ASECNA, SouthPAN, and SDCM).

The built-in professional-grade interference signal detection and elimination algorithms effectively mitigate multiple narrow-band interferences, which significantly improves signal reception performance, particularly in complex electromagnetic environments. In addition, LG580P (03) supports multi-band signals L1, L2, L5, L6 and features built- in RTK + Heading algorithms, significantly enhancing robustness in challenging environments such as dense foliage canopy and urban canyons, enabling high-precision positioning capabilities.

LG580P (03) supports integrity information detection functions such as protection level to assist control decision- making in applications like autonomous navigation. It also features on-chip memory ECC verification and Secure Boot loading mechanisms, providing additional firmware security. In addition, it offers versatile peripheral interfaces including UART, SPI*, I2C*, and CAN* to meet diverse application requirements.

With high precision, low power consumption and a high positioning and heading update rate of up to 20 Hz, LG580P (03) is an ideal choice for high-precision navigation applications, such as intelligent robots, precision agriculture, ADAS, and autonomous driving.
