The embedded atmospheric data system is the most suitable technical solution for obtaining hypersonic vehicle air data. It can provide the measurement of atmospheric parameters such as angle of attack, side slip angle, Mach number and dynamic pressure for the guidance of hypersonic guided vehicles. Benchmark, with the traditional pitot tube type air data system incomparable advantages. The key technologies involved in the embedded atmospheric data system are analyzed. The embedded atmospheric data system of a typical hypersonic vehicle is introduced. The pressure hole layout, system components design and pressure sensor selection of the relevant schemes are introduced emphatically. This paper introduces a method of calculating the embedded atmospheric data based on Kalman filter. The research shows that the algorithm has the characteristics of high precision, strong robustness and adaptability. It is suitable for the application of modern hypersonic vehicle .
