    BHI160BP

    The BHI160BP is an application specific upgrade of the BHI160 family and comes with a Pedestrian Dead Reckoning (PDR) Algorithm that allows Pedestrian Position Tracking at a fraction of the power consumption of GNSS only solutions.

    It is a small, low-power smart sensor that combines an integrated three axis gyroscope, an integrated three axis accelerometer and a programmable microcontroller including an integrated specifically developed algorithm for PDR.

    Bosch Sensortec's BHI160BP can be integrated in devices that use any type of GNSS or any other absolute positioning system, enhancing the system in two aspects, both reducing the system power consumption and improving the robustness of the position tracking whenever the GNSS system suffers from bad signal quality. The BHI160BP allows to significantly reduce the power consumption, by interpolating the path between two position fixes, allowing to keep the GNSS receiver in sleep mode for a longer period of time (power duty cycling).

    Applications

    • Pedestrian always-on position tracking
    • Low-power always-on algorithms for wearables
    • Enhanced position tracking robustness under challenging GNSS signal conditions
    • Supports walking, jogging, and other activities
    • Supports loose coupled synchronization with GNSS module over a generic interface

    Wearable Applications

    When used with a GNSS module, the BHI160BP enables users to take full advantage of pedestrian position tracking with up to 80% saving in system power consumption compared with a typical GNSS-only solution, without compromising on accuracy. Users benefit from a greatly extended battery life and longer charging intervals for wearable applications such as smartwatches and fitness trackers and other mobile devices.

    3 50% till 80% are the typical values of system power saving for standard user walking profile and system 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.
