NaviBlind leverages u-blox ZED-F9P high precision GNSS technology to empower the blind and visually impaired

The u-blox ZED-F9P was the first mass market multi-band receiver to concurrently use GNSS signals from all four GNSS constellations (GPS, GLONASS, Galileo, and BeiDou) with integrated multi-band real time kinematic (RTK) technology to achieve centimeter-level accuracy in seconds - even in challenging environments such as in cities. The u-blox ZED-F9P is also cost-efficient, compact, and has low power consumption, precisely what the NaviBlind business model needed.

The NaviBlind GPS device leverages the u-blox ZED-F9P, which connects to the NaviBlind app via Bluetooth to deliver the essential positioning quality required for allowing blind and visually impaired people to access the outdoor world independently via precise voice navigation. The app also helps the user stay within the bounds of sidewalks and pedestrian crossings to avoid potential danger - such as walking onto car lanes. These features require a very accurate location service that smartphones’ internal location systems can’t possibly deliver. A regular smartphone can produce significant position errors, sometimes more than ten meters.
