GNSS GNSS is a necessary accessory when flying competitions, where it has to be demonstrated that way-points have been correctly passed. The recorded GNSS track of a flight can be used to analyze flying technique or can be shared with other pilots. GNSS is also used to determine drift due to the prevailing wind when flying at altitude, providing position information to allow restricted airspace to be avoided and identifying one's location for retrieval teams after landing out in unfamiliar territory. GNSS is integrated with some models of variometer. This is not only more convenient, but also allows for a three-dimensional record of the flight. The flight track can be used as proof for record claims, replacing the old method of photo documentation.
