GPS  Dead Reckoning module RDR-3300 integrated with Dead Reckoning technology
RoyalTek RDR-3300 is the next generation of RoyalTek GPS module integrated Dead Reckoning technology. The RDR-3300 includes dead reckoning sensors to track your vehicle's course when your GPS signal is blocked for example in urban areas or tunnels. If you lose GPS coverage in areas with tall buildings or tunnels, the RDR-3300 keeps on navigating.
