For several reasons: 1) Each online competition requires a lot of time to setup and support. This directly depends on the number of registered competitors. 2) Paying a small fee is likely to increase the chance the registered participants actually take part in the competition. 3) Cash will be used towards the prizes in each competition and to the overall winners at the end of the season. 4) Technical support of the project costs money (hosting, domain, data storage, etc.)
Wingsuit World is a not-for-Profit organization created by a group of skydivers who are passionate about wingsuit performance competitions. Our goal is to help wingsuit pilots quickly improve their skill level through analyzing wind-cancelled tracks and participating in global online competitions.
Is wind cancellation performed by estimating wind speed and direction during the climb to altitude?
No, the wind data is taken from the GFS forecast issued by NOAA. The system finds the most recent forecast for the time and location of the jump and subtracts the wind from the horizontal speed measured by GPS. Vertical speed and recorded altitude remain unaffected (correction for air density is planned to be implemented at a later date).
Yes! FlySight stores data on a microSD card. Use On-The-Go (OTG) USB cable to connect FlySight (mini-USB port) to your OTG supported mobile device. This allows uploading tracks directly from your phone (why hasn’t everyone been doing that?). You’ll need OTG cable like this one: http://www.amzn.com/B018M8YNDG
