The BHI160BP is an application-specific upgrade of the BHI160 family and comes with a Pedestrian Dead Reckoning (PDR) algorithm that enables pedestrian position tracking at a fraction of the power consumption of GNSS only solutions. BHI160BP integrates a 3-axis gyroscope, a 3-axis accelerometer and a programmable microcontroller together with a PDR-specific algorithm in one single sensor package. The smart sensor enhances the system in two aspects: It reduces the system power consumption and improves the robustness of the position tracking whenever the GNSS signal quality is low.
⁴ Relative position estimation error for 75% of the population of various user profiles and movement profiles (walking, jogging, standing still, etc.) will have a typical error of 10% or better relative to the walked distance. This is the relative error of the BHI160BP PDR algorithm without GNSS assistance.
⁵ Performance measured for 9DOF solution (with attached magnetometer BMM150).
