      1.3.3 Inertial measurement unit (IMU)

      Inertial measurement unit (IMU) is a device that mainly measures angular velocity, orientation, gravitational force and magnetic direction. In an early stage of the development of the IMU, a gyroscope and an accelerometer were usually utilised to provide angular velocity and inertial acceleration. Later on, integration of a magnetometer enabled an IMU to measure magnetic direction. As a result, measurements from an IMU can be more accurate [20]. As all these sensors are able to provide three‐dimensional measurements, the IMU is widely utilised in movable applications, such as for aircraft navigation [398].

      Kinematic model‐based state estimation can often be used to estimate parameters of interest while combining different information available typically in real‐time applications. Let the N sensor measurements be y equals left-bracket y 1 midline-horizontal-ellipsis y Subscript upper N Baseline right-bracket and the unknown states of the dynamic system be x equals left-bracket x 1 midline-horizontal-ellipsis x Subscript upper M Baseline right-bracket.
