Im seabreeze Forum wurde die neue Auwertungssoftware vorgestellt:
I have released a new application for GPS file analysis today. It's free to use, and runs on Mac, Windows, and Linux. It does not have all the features you find in GPSResults or GPS Action Replay, but it's a lot faster when working with large files. It supports files from the GW60 and GW52, the Motion GPS, and u-blox prototype. GT31 users would have to export or convert files to .sbp format first.
Besides fast analysis, another goal was to make posting to the GPS Team Challenge easy. There is a menu option to open a browser window with the results, which has a "Submit" button that will post results to GPSTC.
Results in most GPSTC categories will generally be very close or identical to results obtained with the other programs. In the 2 and 5x10 second categories, results should be identical, except for occasional differences in the last digit that are from rounding errors. In the other categories, results may sometimes vary a bit. For example, both GPSResults (with default settions) and GPSActionReplay filter out speeds below 5 knots for the 1-hour results. GPS Speedreader uses a 0.6 knot filter instead, so 1 hour results can be a bit higher, especially if you were not planing the entire time. Results can also be higher if you use a minimum speed setting on the GPS, which can cause incorrect results with other software.

There's a blog post with screen shots and a few notes at boardsurfr.blogspot.com/2019/05/gps-speedreader.html

The software does not require any license keys. If you like it and want to support the development, "beer money" donations are welcome. There's a Paypal button on the help page at ecwindfest.org/GPS/GPSSpeedreaderHelp.html. Note that the currency is US dollars, so you don't get a big surprise like a certain former dentist who shall remain unnamed .
