Fast SINS Initial Alignment Method Based on Iterative Algorithms in Inertial Frame [PDF]
Mathematical Problems in Engineering, 2020 Iterative algorithms based on saved data have been researched for strapdown inertial navigation system to make the best use of sensor data, and different alignment algorithms can be carried out during the iterative process to fulfil initial alignment. This paper firstly analysed two interactive processes.
