The design and realization of the indication speed measuring system in pilotless aircraft based on micro-controller unit(MCU)are introduced.The hardware and the algorithm of measuring system are elaborated. Aimed at the expression of function of indicated air speed and dynamic pressure
1inear interpolation algorithm is presented.The relative error of the measuring system is within 2%.The test result shows that the measuring system has good stability and it can real-time calculate and output indicated air speed with high precision.
