Quectel has launched the LG680P, a multi-constellation, quad-band GNSS module designed to deliver high-precision positioning across a wide range of applications including precision agriculture, intelligent robots and surveying.
The Quectel LG680P GNSS module is designed to receive signals from multiple global navigation satellite systems, including GPS, GLONASS, Galileo, BeiDou (BDS), QZSS, and NavIC, , as well as multiple SBAS systems (WASS, EGNOS, BDSBAS, MSAS, GAGAN and SDCM). ensuring exceptional positioning accuracy and reliability.
With multi-band GNSS support, it concurrently receives L1, L2, and L5 bands, enhancing signal quality and precision. The module will also support Galileo E6, QZSS L6, and BDS B2b for Precise Point Positioning (PPP) technology, delivering high precision accuracy without requiring for local or broadband connectivity. It represents a major leap in high-precision GNSS technology, combining multi-constellation reception, advanced RTK algorithms, and robust anti-jamming capabilities.
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, LG680P(03) supports L1, L2 and L5 multi-band RTK algorithm solution, significantly improves the module’s robustness in complex scenarios such as urban environments and deep tree cover, supporting the output of high-precision positioning result. In addition, the module supports Galileo E6, QZSS L6, BDS B2b and L-Band for PPP technology.
The LG680P (03) multi-band GNSS module 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 LG680P(03) accommodates users diverse needs with a choice of interfaces including UART, SPI, I2C and CAN.
With high precision, low power consumption and a high positioning update rate up to 20Hz, the LG680P (03) multi-band GNSS module is an ideal choice for high precision navigation applications, such as intelligent robots, precision agriculture, ADAS, and autonomous driving.
The LG680P can achieve horizontal accuracy of up to 0.8 cm + 1 ppm, ensuring a stable and reliable performance even in challenging urban environments, making it an ideal choice for applications such as autonomous lawnmowers, delivery robots, surveying, and precision agriculture. The module has also been tested with dual-band corrections, ensuring backward compatibility with existing systems that rely on dual-band technology. While quad-band corrections provide the most optimized performance, this capability allows the module to seamlessly replace older dual-band systems, offering enhanced precision and futureproofing without requiring immediate infrastructure changes.
The LG680P GNSS module features professional-grade anti-jamming and interference detection algorithms, ensuring signal integrity even in complex electromagnetic environments. Its built-in NIC anti-jamming technology effectively 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.
