All classical microlight and paramotor competitions contain tasks requiring GPS loggers. To derive a pilot score the resulting logger tracks must be analysed. Normal rules also require all tracks to be published as soon as possible.
There are many softwares out there which will read GPS tracks. There are not so many which will reliably provide an analysis of the flight against a typical task set in a microlight and paramotor competition, eg by producing a summary of the times when gates were crossed or turnpoints entered.
