MAX-M8 - Data Sheet
1 Description
1.1 Overview
The MAX-M8 series of concurrent GNSS modules are built on the high performing u-blox M8 GNSS engine in
the industry proven MAX form factor.
The modules can concurrently receive up to three GNSS systems (GPS/Galileo) together with BeiDou or
GLONASS). The MAX-M8 modules recognize multiple constellations simultaneously and provide outstanding
positioning accuracy in scenarios with urban canyon or weak signals. The modules offer high performance even
at low power consumption levels. For even better and faster positioning improvement, the MAX-M8 modules
support augmentation of QZSS and IMES together with WAAS, EGNOS, MSAS, GAGAN.
The MAX-M8 modules support message integrity protection, Geofencing, and spoofing detection with
configurable interface settings to easily fit to customer applications. The MAX form factor allows easy migration
from previous MAX generations.
u-blox MAX-M8 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 ISO16750
standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.
MAX-M8 modules are available in three product variants:
• MAX-M8C is optimized for cost sensitive applications and has the lowest power consumption.
• MAX-M8Q provides best performance for passive and active antennas designs. It is also halogen free
(green) which makes it perfectly suited for consumer applications.
• MAX‑M8W provides best performance and is optimized for active antennas.
The modules combine a high level of integration capability with flexible connectivity options in a miniature
package. This makes it perfectly suited for industrial applications with strict size and cost requirements. The I
2
C
compatible DDC interface provides connectivity and enables synergies with most u-blox cellular modules.
The u-blox MAX-M8 modules can also benefit from the u-blox AssistNow assistance service. The Online service
provides GNNS broadcast parameters, e.g. ephemeris, almanac plus time or rough position to reduce the
receiver’s time to first fix significantly and improve acquisition sensitivity. The extended validity of AssistNow
Offline data (up to 35 days) and AssistNow Autonomous data (up to 3 days) provide faster acquisition after a
long off time.
See section 1.6 for more information concerning the MAX-M8 related AssistNow Assistance.
