u-blox NEO-M9V positioning module

Thursday, 18 November, 2021 | Supplied by: u-blox Singapore Pte Ltd

u-blox’s NEO-M9V global navigation satellite system (GNSS) receiver offers both untethered dead reckoning (UDR) and automotive dead reckoning (ADR). The positioning receiver is suitable for fleet management and micromobility applications that require metre-level positioning accuracy even in challenging GNSS signal environments such as urban canyons.

Using inertial sensor measurements, UDR offers a smooth navigation experience in dense urban environments by bridging gaps in GNSS signal coverage and mitigating the impact of multipath effects caused by GNSS signals that bounce off buildings. ADR further increases positioning accuracy in demanding environments by including the vehicle speed in the sensor fusion algorithm. Offering both UDR and ADR on the same module delivers both good positioning performance and design flexibility, allowing users to provide optimal solutions for their customers on a case-by-case basis.

The product also features dynamic models optimised for both cars and e-scooters. By adapting the algorithms of the dead reckoning solution to the behaviour of these use cases, these dynamic models further increase the quality of the position reading.

The device is based on u-blox’s M9 GNSS technology platform. Its ability to track up to four GNSS constellations maximises the number of GNSS satellites within its line of sight at any given moment. Integrated SAW and LNA filters offer good interference mitigation for a robust solution, accelerating product design and shortening time to market. Compatibility with the NEO form factor reduces migration efforts for those upgrading existing designs.
