Thanks to its GNSS chip, u-blox’ M9 technology platform and the NEO-M9N, the first module based on this platform, can receive signals from up to four GNSS constellations (GPS, Glonass, Beidou, and Galileo) concurrently. Thus, it can achieve high positional accuracy even in difficult conditions such as deep urban canyons. 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.
The M9 also features a 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, for example when a cellular modem is co-located with the NEO-M9N.
u-blox has developed the M9 as a follow-on from the company’s successful u-blox M8 GNSS platform, offering more robust meter-level positioning technology and security features to protect the integrity of applications in the automotive, telematics, and UAV markets.
Users of the u-blox M9 will therefore 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 very little change to the board design.
The introduction of the u-blox M9 is accompanied by the release of the Explorer Kit M9 (XPLR-M9) development board. The plug-and-play device is supplied with u-start software, which includes a number of 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.
