³ 50% till 80% are the typical values of system power saving for standard user walking profile andsystem including typically available GNSS module characteristics. Actual power saving usually vary depending on the application and GNSS module.
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).
