DP0201 GNSS introduces UDR technology (Untethered Dead Reckoning) which provides continuous navigation without requiring speed information from the vehicle.
This technology brings continuous positioning in urban environments, even to devices with antennas installed within the vehicle. Useful positioning performance is also available during complete signal loss, for example in short tunnels or parking garages. With UDR, positioning starts as soon as power is applied to the module, before the first GNSS fix is available.
The NEO-M8U includes u-blox’s latest generation GNSS receiver, which adds Galileo to the multi-constellation reception that already includes GPS, GLONASS, BeiDou and QZSS. The module provides high sensitivity and fast GNSS signal acquisition and tracking.
