Reverse Engineering iLap Racing Transponders for Inter-operability
[Scroll to the bottom if you just want to know how it works]
Being an avid drone enthusiast it’s been difficult not to notice and get involved in the explosion of FPV racing recently. At these events, drones are timed around the track using infra-red transponders such as the one on the right. This transponder is part of the iLap racing system – a particularly well designed system albeit somewhat expensive. Hence, we’ve been developing our own race transponder/timing system (using a different protocol) but wanted it to be interoperable with iLap and recognise both types of transponders on the gates. Reverse engineering is explicitly permitted in the EU and USA for this purpose.
