1.1 Overview

The u-blox concurrent CAM-M8 series GNSS antenna modules benefit from the exceptional

performance of the u-blox M8 multi-GNSS (GPS/QZSS, GLONASS, GALILEO and BeiDou) engine in

an industry proven form factor. The CAM-M8 modules offer high sensitivity and strong signal levels

in an ultra-compact form factor.

The CAM-M8 series 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 in scenarios where urban canyon or weak signals are involved. For

even better and faster positioning improvement, the CAM-M8 series supports augmentation of

QZSS, GAGAN and IMES together with WAAS, EGNOS, and MSAS. The CAM-M8 series also

supports message integrity protection, geofencing, and spoofing detection with configurable

interface settings to easily fit to customer applications.

Incorporating the CAM-M8 modules into customer designs is simple and straightforward, thanks to

the embedded GNSS chip antenna, a small footprint of 9.6 x 14.0 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.

Despite the miniature size, the GNSS chip antenna in the CAM-M8 series performs extremely well

compared to traditional patch antennas. The omni-directional radiation pattern increases flexibility

for device installation. Optionally, CAM-M8 modules can be connected to an external GNSS antenna.

The SMD design keeps manufacturing costs to a minimum and the small mass ensures high

reliability.

be followed in order to maintain optimal performance of the on-board GNSS chip antenna. For

more information, see the CAM-M8 Hardware Integration Manual [1].

The CAM-M8 series modules target industrial and consumer applications that require concurrent

GPS/Galileo and GLONASS or GPS/Galileo and BeiDou reception. The CAM-M8C is optimized for cost

sensitive applications and has the lowest power consumption, while the CAM-M8Q provides best

performance. The CAM-M8 series is form-factor compatible to UC530 and UC530M modules,

allowing the upgrade of existing designs with minimal effort.

The CAM-M8 series modules use GNSS chips qualified according to AEC-Q100, are manufactured in

ISO/TS 16949 certified sites, and fully tested on a system level. Qualification tests are performed as

stipulated in the ISO 16750 standard: “Road vehicles – Environmental conditions and testing for

electrical and electronic equipment”.
