I finally found time to publish the new BLM version. I decided to make it a new major version (3.0.265).
Aside of a face lift and introduced version check at startup, this version contains a feature to detect the take-off and landing positions. While we have intensively tested the feature during the last big competitions (Europeans 2015 and WAG Dubai), please use the detected positions with reasonable care.
The algorithm to detect take-off and landing is based on some work from Flytec and uses the barometric altitude, variometer and GPS ground speed.
Please note that sometimes multiple take-offs and landings could be detected. (in low wind conditions or if the balloon is moved)
You can download the new version from the BLM page.
