u-blox has released the NEO-M9V GNSS receiver. The first positioning receiver to provide both UDR and ADR, the device is ideal for fleet management and micromobility applications that demand reliable meter-level positioning accuracy even in harsh GNSS signal environments such as urban canyons.


Vehicle fleet managers looking to decrease costs and lower their carbon footprint rely on accurate positioning and navigation data to lessen fuel consumption. Furthermore, precise odometry data is critical to fleet managers for billing and compliance.


Micromobility operators must accurately locate their devices to service the individual bikes and scooters. Locating vehicles on the other wrong of the street can force drivers to make lengthy detours to arrive at their intended destination, incurring extra cost, lower service quality, and polluting the air. Accurate positioning is also crucial to geofence their operation in compliance with local regulations.


Utilising inertial sensor measurements, UDR provides a smooth navigation experience in dense urban environments by bridging gaps in GNSS signal coverage and alleviating the impact of multipath effects created by GNSS signals that bounce off buildings. ADR further increases positioning accuracy in tough environments by incorporating the vehicle speed into the sensor fusion algorithm.


It also offers dynamic models optimised for both cars and e-scooters. By adjusting the algorithms of the dead reckoning solution to the behaviour of these cases, these dynamic models further enhance the quality of the position reading.


Based on the robust u-blox M9 technology platform the device is based on the M9 GNSS technology platform. Its capability to track up to four GNSS constellations maximises the number of GNSS satellites within its line of sight at any particular moment. Integrated SAW, and LNA filters provide excellent interference mitigation for a robust solution, speeding product design and reducing time to market. And compatibility with the popular NEO form factor decreases migration efforts for customers upgrading current designs.


“We expect customers to immediately recognise the value the NEO-M9V delivers. Tailored to the needs of industrial markets, the module offers a fast time to market with increased design flexibility and reliable meter-level positioning performance right where it matters most: in urban centres,” says Mathias Vetter, principal product manager for consumer and industrial tracking at u-blox.
