UBX-M9140-KA-DR is a robust u-blox M9 single-band GNSS chip, which provides exceptional sensitivity and acquisition times for all L1 GNSS systems. The u-blox M9 standard precision GNSS platform, delivering meter-level accuracy, succeeds the well-known u-blox M8 product range. The sophisticated built-in algorithms fuse IMU data, GNSS measurements, wheel ticks, and vehicle dynamics to provide optimal positioning accuracy where GNSS alone would fail. A GNSS-only second output is also available, along with the dead reckoning solution, to support a variety of third-party applications.

The chip supports concurrent reception of four GNSS constellations, increasing the availability of satellite measurements. The high number of visible satellites enables the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as in deep urban canyons.

The chip offers good performance even in difficult multipath environments such as tunnels or underground parking garages. UBX-M9140-KA-DR is the ultimate solution for modern automotive applications where control and position availability are keys to success.

In addition to RF-based jamming and spoofing detection, UBX-M9140-KA-DR implements sensor-based spoofing detection and is designed to inform applications about possible security attacks.

UBX-M9140-KA-DR is qualified according to AECQ100 and is manufactured in ISO/TS 16949 certified sites.
