`ctrw` is an R package that fits a continuoustime random walk model in statespace form to filter Argos satellite location data. Template Model Builder (`TMB`) is used for fast estimation. The Argos data can be either (older) Least Squaresbased locations or (newer) Kalman Filterbased locations with error ellipse information. Separate measurement models are used for these two data types. The model estimates two sets of location states: 1) corresponding to each observation, which are irregularly timed; and 2) corresponding to regular time intervals specified by the user.
