Know your oblu
Are you keen to know why four IMUs and why on the single side of PCBs are chosen for oblu, and how to make oblu power optimized.
Evolution of a multi-IMU shoe-mounted inertial navigation system is presented in this article. The overall study suggests that by selecting a well-designed operating point, a multi-IMU system can be made cost, size and power efficient without practically affecting its superior positioning performance.
The superior positioning performance and enhanced power efficiency enable many critical applications requiring infra-free indoor positioning. Innovative products and services around such low-cost PDR sensor would fuel further big innovations, and unleash its mass market applications.
