u-blox CAM-M8 GNSS Antenna Modules

u-blox CAM-M8 GNSS Antenna Modules are designed to offer high sensitivity and strong signal levels in an ultra-compact form factor. These modules utilize concurrent reception of up to three GNSS systems (GPS/Galileo together with BeiDou or GLONASS), recognize multiple constellations simultaneously, and provide outstanding positioning accuracy. The CAM-M8 modules support the augmentation of QZSS, GAGAN, and IMES together with WAAS, EGNOS, and MSAS for faster positioning improvement. These modules feature an embedded GNSS chip antenna, a small footprint of 9.6mm x 14mm x 1.95 mm, and interference suppression for simple and straightforward design. The CAM-M8 modules are used in industrial and consumer applications that require concurrent GPS/Galileo and GLONASS or GPS/Galileo and BeiDou reception. The CAM-M8C antenna module is optimized for cost-sensitive applications with the lowest power consumption and the CAM-M8Q antenna module provides the best performance.
