Urban canyons, tunnels, parking garages and severe overcast all pose a significant problem to navigation systems. Dead reckoning (DR) technology improves positioning accuracy for navigation systems when satellite signal conditions are comprised.

Autonomous Dead Reckoning

Autonomous dead reckoning modules make use of multiple micro-electromechanical systems (MEMS) sensors and a high performance satellite receiver to derive dead reckoning position coordinates from the sensor array when satellite signal is compromised.  Autonomous DR enables 100% coverage and is perfect for high-accuracy navigation applications.

There are several Dead Reckoning (DR) modules on the market, each with varying levels of performance. How do you select the right one? 


Five Things to Consider:

  • Radio Noise filter – find out what to look for to improve location accuracy. 
  • Temperature stability – what to look for to ensure reliability at extreme temperatures
  • RF sensitivity – how to ensure the module has the highest level of sensitivity
  • Antenna status – ability for application to determine if the antenna is connected and working
  • Embedded sensors – seven degrees of freedom (DoF) versus 6-axis sensor system
