CAM-M8 - Data Sheet1 Functional description1.1OverviewThe u-blox concurrent CAM-M8 series GNSS antenna modules benefit from the exceptional performance of theu-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 togetherwith BeiDou or GLONASS), recognize multiple constellations simultaneously, and provide outstanding positioningaccuracy in scenarios where urban canyon or weak signals are involved. For even better and faster positioningimprovement, the CAM-M8 series supports augmentation of QZSS, GAGAN and IMES together with WAAS,EGNOS, MSAS. The CAM-M8 series also supports message integrity protection, geofencing, and spoofingdetection with configurable interface settings to easily fit to customer applications.Incorporating the CAM-M8 modules into customer designs is simple and straightforward, thanks to theembedded GNSS chip antenna, a small footprint of 9.6 x 14.0 x 1.95 mm, and sophisticated interferencesuppression that ensures maximum performance even in GNSS-hostile environments. The low powerconsumption, 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 totraditional 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 keepsmanufacturing costs to a minimum and the small mass ensures high reliability.Because the customer PCB is part of the antenna solution, some PCB layout design rules should be followedin order to maintain optimal performance of the on-board GNSS chip antenna. For more information seethe CAM-M8 Hardware Integration Manual [1]The CAM-M8 series modules target industrial and consumer applications that require concurrent GPS/Galileoand GLONASS or GPS/Galileo and BeiDou reception. The CAM-M8C is optimized for cost sensitive applicationsand has the lowest power consumption, while the CAM-M8Q provides best performance. The CAM-M8 series isform-factor compatible to UC530 and UC530M modules, allowing the upgrade of existing designs with minimaleffort.The CAM-M8 series modules use GNSS chips qualified according to AEC-Q100, are manufactured in ISO/TS16949 certified sites, and fully tested on a system level. Qualification tests are performed as stipulated in theISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronicequipment”.1.2Product featuresUBX-15031574 - R02Production InformationFunctional descriptionPage 5 of 28

CAM-M8 - Data Sheet1.4Block diagramFigure 1: CAM-M8Q/C block diagram1.5Supported GNSS ConstellationsThe CAM-M8 series GNSS modules are concurrent GNSS receivers which can receive and track multiple GNSSsystems: GPS, Galileo, GLONASS and BeiDou. Owing to the dual-frequency RF front-end architecture, eitherGLONASS or BeiDou can be processed concurrently with GPS and Galileo signals providing reception of threeGNSS systems. By default the M8 receivers are configured for concurrent GPS and GLONASS, including SBASand QZSS reception. If power consumption is a key factor, then the receiver should be configured for a singleGNSS operation using GPS, Galileo, GLONASS or BeiDou and disabling QZSS and SBAS. The module can beconfigured to receive any single GNSS constellation or within the set of permissible combinations shown below.GPSGalileoGLONASSBeiDou –– – – – – –– –– –– –– Table 2: Permissible GNSS combinations ( enabled)The augmentation systems: SBAS and QZSS can be enabled only if GPS operation is configured.Galileo is not enabled as the default configuration.1.5.1 GPSThe u-blox CAM-M8 series positioning modules are designed to receive and track the L1C/A signals provided at1575.42 MHz by the Global Positioning System (GPS).1.5.2 GLONASSThe CAM-M8 modules can receive and process GLONASS concurrently with GPS or BeiDou.

CAM-M8 - Data SheetM8 positioning modules are designed to receive and track the L1OF signals GLONASS provided at 1602 MHz k*562.5 kHz, where k is the satellite’s frequency channel number (k –7,., 5, 6). The ability to receive andtrack GLONASS L1OF satellite signals allows design of GLONASS receivers where required by regulations.In order to take advantage of GPS and GLONASS, dedicated hardware preparation must be taken during thedesign-in phase, see the CAM-M8 Hardware Integration Manual [1] for u-blox design recommendations.1.5.3 BeiDouThe CAM-M8 series positioning modules can receive and process the B1I sig
