Height data fusion based on the information of ultrasonic array sensor and SINS/GPS

A VAV ground height measurement system based on ultrasonic array sensor and SINS/GPS is proposed. First, a new ultrasonic array sensor is designed. On the basis of the altitude of the last time, the height of the current time can be obtained with the acceleration and velocity information of SINS/GPS. Then, with the combination of the measurement height of ultrasonic array sensor to the federated information fusion. According to the working characteristics of the two systems, dynamic distribution coefficients are adopted. Finally, the simulation of the altitude measurement system is carried out. The simulation results show that the system can measure the height of VAV effectively and it has the application value in engineering.
