SBAS Positioning module | M680

Dual-band SBAS submeter positioning module

Star based enhancementHigh integrityAviation StandardsLow-Power consumption

The M680 module is based on a 12nm low-power RF baseband integrated SoC chip, supporting BDS, GPS, Galileo, GLONASS, and QZSS satellite signal reception. This module is equipped with Satellite Based Augmentation System (SBAS) positioning function, which can achieve sub meter positioning accuracy even without ground RTK/CORS services. Can meet the high-precision positioning requirements of various scenarios such as vehicles, robots, drones, ships, etc.
