NavCleaner (OFOS Edition) for processing raw Posidonia USBL datagrams

The NavCleaner (OFOS Edition) is a program that filters, smooths and interpolates USBL navigation data. The NavCleaner (OFOS Edition) is optimised to process the navigation tracks of the AWI OFOS and OFOBS instruments but it can be used to process Posidonia USBL data from other instruments as well. As input it only requires a text file containing raw USBL datagrams. The program outputs comma-separated files containing the filtered, smoothed and 1 Hz interpolated navigation timeseries (both geographic coordinates and UTM/UPS coordinates). All calculations are done internally on projected coordinates using the most relevant WGS84 UTM/UPS zone in order to minimize errors. If used with the OFOS / OFOBS platforms, the NavCleaner (OFOS Edition) can optionally read and interpolate the altimeter data from the photos' EXIF metadata, and compute the coordinates for every photo as well as for every observations in the dive report (Excel format). A dive report template is provided, which can also be used with other platforms.
