Quectel LG680P quad-band GNSS module

Quectel Wireless Solutions has launched the LG680P — a multi-constellation, quad-band GNSS module designed to deliver high-precision positioning across a range of applications including precision agriculture, intelligent robots and surveying.

The GNSS module is designed to receive signals from multiple global navigation satellite systems, including GPS, GLONASS, Galileo, BeiDou (BDS), QZSS and NavIC, for enhanced positioning accuracy. With multi-band GNSS support, it concurrently receives L1, L2 and L5 bands, boosting signal quality and precision. The module will also support Galileo E6, QZSS L6 and BDS B2b for Precise Point Positioning (PPP) technology, delivering accuracy without requiring local or broadband connectivity.

The product can achieve horizontal accuracy of up to 0.8 cm + 1 ppm for stable performance even in challenging urban environments. It has also been tested with dual-band corrections, for backward compatibility with existing systems that rely on dual-band technology. While quad-band corrections provide the most optimised performance, this capability allows the module to replace older dual-band systems, offering enhanced precision and futureproofing without requiring immediate infrastructure changes.

The GNSS module features professional-grade anti-jamming and interference detection algorithms, maintaining signal integrity even in complex electromagnetic environments. Its built-in NIC anti-jamming technology suppresses multiple narrow-band interferences, enhancing signal reception and stability. The module also supports fast positioning updates with a refresh rate of up to 20 Hz, enabling real-time tracking and improved responsiveness.

With a 22 x 17 mm footprint, the module adopts a widely used industry form factor and supports multiple interfaces, including UART, SPI, I2C and CAN. It is also designed for optimised signal reception, with support for external active antennas to enhance positioning accuracy. Its low power consumption makes it an energy-efficient solution suitable for battery-operated devices.
