For realizing precise measurement of climbing speed of quadrotors, a new detection method is presented. Firstly it applies the weighted average method and mean filter method to measure height, then it uses smooth noise-robust differentiators to calculate the climb speed,and finally it obtains accurate information by means of the real-time data acquisition and processing. The experimental results based on the MS5611-01BA barometer sensor from MEAS show that:the climbing speed precision obtained by smooth noise-robust differentiators is improved obviously, the standard deviation value is only about 34%of that gets by central differences method, and 13% less than that gets by Lanczos differentiators method, it has better robustness, and meets the requirements of practical applications.
