Fixed a problem with export to the latest version of GoogleEarth


Version 6.139 PC:

Fixed a glitch with positional data and Alpha categories


Version 6.138 PC:

FIT-file format supported, handling of files without satellite information improved


Version 6.123 PC, 5.36 Mac:

UBX corrupted file handling improved


Version 6.122 PC, 5.35 Mac:

24 hour results reviewed, upload of all run and track points added


Android 2.3.3 Testversion


Version 6.105 PC:

Custom website upload added, filter-settings no longer saved


Version 6.104 PC, 5.31 Mac:

GPX-reader improved, UBX support for 10Hz sampling rate improved, maximum SDoP limit implemented (1.5knots), color coded tracks (Mac-version)


Version 6.96 PC:

Averaging files from Doppler-units with different firmware versions possible. New gated categories (250m and 500m) with given start-line only.


Version 6.90 PC:

Improved support of UBX-format (from U-Blox chipsets), user defined time-categories extended for shorter runtimes (s has to be added after the number, without s the number is taken as number of minutes as before, for example 13s gives results for 13 second runs)
