 In-flight alignment method of navigation system based on microelectromechanical systems sensor measurementJianwei Liu and Tao Zhao International Journal of Distributed Sensor Networks, 2019, vol. 15, issue 4, 1550147719844929 Abstract: Inertial navigation systems based on microelectromechanical systems (MEMS) sensors offer advantages that include small size, light weight, low power consumption, strong environmental adaptability, and low cost. These advantages make these sensors particularly suitable for application to precision-guided munitions, which commonly have poor launching environments, strict volume and power consumption requirements, and high cost sensitivity. In this article, the key technologies required for missile-borne integrated navigation systems and the solutions for the problems with each of these technologies are analyzed. An attitude angle estimation method for satellite-assisted MEMS measurement information is proposed that solves the in-flight alignment problem. A high-precision combination of satellite positioning and microinertial navigation is realized through design of a new integrated algorithm framework. The experimental results show that the proposed methods can effectively solve the current problems in guided ammunition navigation.
