GPS trace

When we talk about 'GPS traces', we are talking about a log file containing height and position for the whole flight, called an IGC file. Conveniently, all gliders at Gransden (including CU) are fitted with FLARM units that have loggers built in. Alternatively you can use your own logger. The FR300 is popular.

If using the FLARM unit as your logger, make sure a microSD card is present before launching. Afterwards, speak to an instructor about recovering your log file from the SD card. It should download to the SD card, which you can then remove and take the '.igc' file off of it on the computers in the briefing room. Then send that IGC file to the committee to get it scored in cuppers or to submit for trophies.

It's worth noting that looking at your own GPS traces can be a very valuable way to analyse your flying. There are several free IGC viewers online which will allow you to replay your flight minute by minute, and potentially show you where you went wrong. If you're confused about any of this, speak to some experienced members who will be happy to help.
