PRODUCT DESCRIPTION
NS-DR is S1722DR8 GPS Dead-Reckoning receiver in easy to use breakout board form. 
 
NS-DR has fast auto-calibration process, much easier to use than other automotive DR receivers on the market.
 
Its on-board barometric pressure sensor provides highly accuracy altitude information, offers superior altitude result for differentiating floor level of multi-story parking garage or stacked highway when compared to other noisy accelerometer-based methods. 
 
The NS-DR is ideal for automotive applications having access to speedometer signal requiring highest accuracy continuous navigation with 100% availability.
  
For GPS dead-reckoning applications without access to speedometer signal use NS-ODR.
