Abstract :
We present an adaptive heuristic algorithm for data filtering aimed to measurements of accelerations for probes entering a planetary atmosphere. The filter is based on properties of the median and the quantiles, and its design takes into account the presupposed properties of the signal, in order to achieve a higher precision of the recovered signal. The adaptive parameter is the filtering window width. The adaptation is based on the statistical properties of the signal and on heuristic rules
