For Officials

Logger management
The logger writes a IGC file to the SD card. The igc file is mostly compatible with the FAI IGC specification, but it does not intend to be 100% compatible. Nevertheless it is ensured, that the file can be loaded by all common mapping software (Tested with OziExplorer, CompeGPS and Touratech QV). Please be aware that altitudes are stored QNE. If you wish to have a detailed specification of the file format including the custom records for marker drop and goal declaration please feel free to contact Marc André .
In case of a lost or broken SD card the logger can be downloaded using a USB cable.

Logger track download
In general no utility is needed for track download, as the files can directly be accessed from the SD card. Nevertheless the Logger Downloader utility was written by Marc André for simplifying and automating the download process and file renaming while also applying quality control.

Other software the support balloon loggers
The following software are known to handle the balloon loggers natively:

  • eKLIPS (most famous software by Garry Lockyer)
  • BFA Scoring (by Mike Gilligan)
  • Boxy (analysis software by Bob Fisch)
  • FlightAnalyzer (analysis software by Toni Martínez Colom)

In addition GPSBabel can be used to convert the IGC files into almost all existing track file formats.

Documentation and Training
The balloon loggers Quick Guide is provided on this page in Word format. This allows you to modify it for your needs. (e.g. add specific logger failure procedures).

Further a task sheet can be downloaded to provide a training. Pilots may use and try out how to declare a goal and drop a marker. Officials may then download and analyse the data, and even give feedback to the pilots whether they operated the logger properly.
