The Balloon Live project started in 2018 as a follow-up project to replace the FAI Balloon Competition Loggers introduced in 2009 by the New Technology Subcommittee of the FAI Ballooning Commission. The project has a larger scope. It replaces the existing loggers by a mobile app and an additional sensor box to guarantee a constant and equal quality of the position (GPS) and altitude (GPS and barometric) measurements. Additionally the live transmission of the data becomes reality and opens a lot of new possibilities for live coverage and tracking of the competition. Watchmefly.net is an essential part of the project as platform for data recording, visualisation and scoring.
