The ultra-robust M9 technology platform will suit demanding automotive and high-end telematics.

U-blox, a global provider of positioning and wireless communication technologies, has launched its new ultra-robust meter-level M9 global positioning technology platform, designed for demanding automotive, telematics and UAV applications.

Because of the high-performance GNSS UBX-M9140 chip, the M9 technology platform and the NEO-M9N (the first module based on the platform) can receive signals from up to four GNSS constellations (GPS, GLONASS, Beidou and Galileo) concurrently. It can achieve high positional accuracy even in difficult conditions such as deep urban canyons, u-blox said in a press release.

The u-blox M9 offers a position update rate of up to 25 Hz, enabling dynamic applications like UAVs to receive position information with low latency. It also features special filtering against RF interference and jamming, spoofing detection and advanced detection algorithms that enable it to report fraudulent attacks quickly so that users’ systems can react to them in a timely fashion.

A SAW (surface acoustic wave) filter combined with an LNA (low noise amplifier) in the RF path is integrated in the NEO-M9N module. This setup guarantees normal operations even under strong RF interferences, such as when a cellular modem is co-located with the NEO-M9N.

“We’ve developed the u-blox M9 as a follow-on from our very successful u-blox M8 GNSS platform, offering even more robust meter-level positioning technology and security features to protect the integrity of applications in the automotive, telematics, and UAV markets,” said Bernd Heidtmann, product manager, Product Strategy GNSS, Product Center Positioning, at u-blox.

Users of the u-blox M9 will benefit from it being part of the wider u-blox product family, which means that developers will be able to design a single PCB and then migrate to a different positioning technology — such as dead-reckoning augmenting GNSS technology — with little change to the board design.

Explorer kit released

U-blox has also released the Explorer Kit M9 (XPLR-M9), a development board for designers who want to assess the technology. The miniature plug-and-play device is supplied with user-friendly u-start software, which includes preset scenarios to enable users to explore the performance of the new device.

The u-blox M9 technology platform complies with the ISO/TS 16949, ISO 16750, AEC-Q100 standards. Engineering samples of the NEO-M9N, the first module based on the M9 platform, the UBX-M9140 high-performance chip, and the Explorer Kit are available now.
