    Complexity for these models will then be chosen according to the needed performance and the type of application considered. Ability to define this model is part of sensors and IMU manufacturers know-how. Sensors and IMU models are computed in factories through a dedicated calibration sequence using multi-axis turntables and climatic chambers.

  3. Inertial navigation system - Wikipedia

    en.wikipedia.org/wiki/Inertial_navigation_system

    An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the ...

    Some equipment was deleted (e.g., the Azusa tracking system was deleted from later IUs), some equipment was added (e.g., a fourth battery for longer missions), and other components were moved around. These images also show that some components (e.g., batteries, the ST-124 inertial platform) were installed in the IU after it had been stacked in ...

    en.wikipedia.org/wiki/GPS_tracking_unit

    A GPS tracking unit, geotracking unit, satellite tracking unit, or simply tracker is a navigation device normally on a vehicle, asset, person or animal that uses satellite navigation to determine its movement and determine its WGS84 UTM geographic position (geotracking) to determine its location. [1]

  6. Position sensor - Wikipedia

    en.wikipedia.org/wiki/Position_sensor

    A position sensor is a sensor that detects an object's position. A position sensor may indicate the absolute position of the object (its location) or its relative position (displacement) in terms of linear travel, rotational angle or three-dimensional space. Common types of position sensors include the following: Capacitive displacement sensor

  7. Guidance system - Wikipedia

    en.wikipedia.org/wiki/Guidance_system

    The Atlas guidance system was to be a combination of an on-board autonomous system, and a ground-based tracking and command system. This was the beginning of a philosophic controversy, which, in some areas, remains unresolved. The self-contained system finally prevailed in ballistic missile applications for obvious reasons.

  8. Inertial reference unit - Wikipedia

    en.wikipedia.org/wiki/Inertial_reference_unit

    An inertial reference unit (IRU) is a type of inertial sensor which uses gyroscopes (electromechanical, ring laser gyro or MEMS) and accelerometers (electromechanical or MEMS) to determine a moving aircraft’s or spacecraft’s change in rotational attitude (angular orientation relative to some reference frame) and translational position (typically latitude, longitude and altitude) over a ...

    [65] [66] The actual position estimation can be found as the maximum of a 2-d probability distribution which is recomputed at each step taking into account the noise model of all the sensors involved and the constraints posed by walls and furniture. [67]
