New Registration Instructions

  • Records Position, Altitude and Ground Speed every second
  • Can log over 100 hours of data
  • Self contained no other devices required
  • Comprehensive Windows software to analyze logs and view in Google Earth

The SkyTraceGPS is a small on-board device which records the latitude, longitude, ground speed and altitude every second. Each time the SkyTraceGPS is powered up it starts a new log file. These log files can be downloaded to a Windows PC where the data can be analyzed and viewed in Google Earth.

More than just an altitude logger. Typical altitude loggers show various altitude and time calculations such as climb rate, the SkyTraceGPS can also show climb angle, ground speed, distance flown, track angle and more. Now you can see the speed at minimum sink, the climb angle at maximum climb rate, sink rate at a specific speed and much more. What happened to the sink rate and speed when you added 5deg camber? Now you know!

The export to Google Earth is not just for pretty pictures. Click on any point on the flight path and see the data for that point: altitude, climb/sink rate, climb/sink altitude, speed and more. Catch a big thermal way down wind? Now you can see the ground features below the plane where you found the lift.

See for yourself. Go to the downloads page and try out the SkyTraceGPS software (you can load the saved filght file) and the Google Earth kml file.
