# GNSS LG680P (03) Please accept cookies to access this content. ## Summary - High-precision multi-band GNSS module - 22 mm × 17 mm × 2.7 mm - Approx. 2.3 g - Operating temperature: -40°C to +85°C - Supports GPS + GLONASS + Galileo + BDS + QZSS + NavIC ## Key features - Concurrent reception of multi-constellation signals: GPS, GLONASS, Galileo, BDS, QZSS, NavIC and SBAS - Multi-band GNSS signals: L1, L2, L5 and L6 - Galileo E6, QZSS L6, BDS B2b and L-Band* for PPP technology - High positioning update rate up to 20Hz - Built-in professional-grade NIC anti-jamming unit to suppress multiple narrow-band interferences - Abundant interfaces: UART, SPI*, I2C* and CAN* - AGNSS* technology - Features RTKHOLD – retains centimeter-level accuracy for up to 10 minutes after connection loss ## Overview LG680P (03) is a full-constellations, full-bands 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, LG680P (03) supports multi-band signals L1, L2, L5, L6 with built-in RTK algorithms, significantly enhancing robustness in challenging environments such as dense foliage canopy and urban canyons, enabling high-precision positioning. It also supports Galileo E6, QZSS L6, BDS B2b, and L-Band* frequencies for PPP technology. LG680P (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 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.
