What is the Pedestrian Dead Reckoning Accuracy that can be Achieved with Today's MEMS Sensors, and Why Is It Important? Andrew Taylor, Becky Oh, George Hsu September 2014
The Indoor Navigation market is forecasted to grow from $30 million in 2013 to $12.9 billion in 2018. While there are many technologies being leveraged to provide indoor navigation, each has barriers that hinder wide scale adoption of a highly accurate solution. As such, there is a shift towards using multiple technologies together to provide a hybrid solution. The most promising of these is the combination of Wi-Fi, Bluetooth, Cellular, and motion MEMS sensors, namely sensor fusion of gyroscopes, accelerometers, and magnetic sensors.The accuracy one can achieve with today’s MEMS sensors found in mobile phones is presented in this paper along with what effect this accuracy has on integration with other RF signals.
