The REYAX RYM8838 GPS/Glonass/SBAS/QZSS/Galileo/BeiDou Untethered Dead Reckoning(UDR) Mini PCIe Card introduces the Untethered Dead Reckoning (UDR) technology, which provides continuous navigation without requiring speed information from the vehicle. This innovative technology brings the benefits of dead reckoning to installations previously restricted to using GNSS alone and significantly reduces the cost of installation for after-market dead reckoning applications.
