Schematic overview of the principles of a state-space model as applied to the correction of sampling errors in flight height data. The movement (or state) process accounts for the distribution of true flight heights. The observation process introduces sampling errors of various origins (cf. “Review of the sources of error” in “Background”) and yields the recorded flight heights. It also accounts for the sampling schedule. By fitting this model to recorded flight height time series, we can retrospectively compute the corrected flight height, an estimate of the true flight height
