  2. Accelerometer - Wikipedia

    en.wikipedia.org/wiki/Accelerometer

    An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall and is the acceleration felt by people and objects. [2] Put another way, at any point in spacetime the equivalence principle guarantees the existence of a local inertial frame, and an accelerometer measures the acceleration relative to that frame. [4]

  3. Inertial navigation system - Wikipedia

    en.wikipedia.org/wiki/Inertial_navigation_system

    Angular accelerometers measure how the vehicle is rotating in space. Generally, there is at least one sensor for each of the three axes: pitch (nose up and down), yaw (nose left and right) and roll (clockwise or counter-clockwise from the cockpit). Linear accelerometers measure non-gravitational accelerations [22] of the vehicle. Since it can ...

  4. Inertial measurement unit - Wikipedia

    en.wikipedia.org/wiki/Inertial_measurement_unit

    The accuracy of the inertial sensors inside a modern inertial measurement unit (IMU) has a more complex impact on the performance of an inertial navigation system (INS). [16] Gyroscope and accelerometer sensor behavior is often represented by a model based on the following errors, assuming they have the proper measurement range and bandwidth: [17]

  5. Guidance, navigation, and control - Wikipedia

    en.wikipedia.org/wiki/Guidance,_navigation,_and...

    In addition to relative position, the IMUs contain accelerometers which can measure acceleration in all axes. The position data, combined with acceleration data provide the necessary inputs to "track" motion of a vehicle. IMUs have a tendency to "drift", due to friction and accuracy.

  6. Dead reckoning - Wikipedia

    en.wikipedia.org/wiki/Dead_reckoning

    With the increased sensor offering in smartphones, built-in accelerometers can be used as a pedometer and built-in magnetometer as a compass heading provider. Pedestrian dead reckoning ( PDR ) can be used to supplement other navigation methods in a similar way to automotive navigation, or to extend navigation into areas where other navigation ...

    In a 2019 study, 18 senior citizens took a stroll on some treadmills while armed to the hilt with fitness trackers. Commercial fitness trackers are being used for all kinds of things other than ...

  8. PIGA accelerometer - Wikipedia

    en.wikipedia.org/wiki/PIGA_accelerometer

    The PIGA was based on an accelerometer developed by Dr. Fritz Mueller, then of the Kreiselgeraete Company, for the LEV-3 and experimental SG-66 guidance system of the Nazi era German V2 (EMW A4) ballistic missile and was known among the German rocket scientists as the MMIA "Mueller Mechanical Integrating Accelerometer". This system used ...
