u-blox M8 concurrent GNSS antenna modules

CAM-M8 concurrent GNSS antenna module
The u-blox CAM-M8 chip antenna modules have the exceptional performance of the u-blox M8 multi-GNSS (GPS/QZSS, GLONASS and BeiDou) engine in an industry proven form factor. The CAM-M8 series delivers high sensitivity and minimal acquisition times in an ultra compact form factor.

Incorporating the CAM-M8 series modules into customer designs is simple and straightforward, thanks to the embedded GNSS antenna, low power consumption, small footprint of 9.6 x 14 x 1.95 mm, and sophisticated interference suppression that ensures maximum performance even in GNSS-hostile environments. The low power consumption and thin design allow end devices to be slimmer and smaller.
