Hello there, I would like to know what accuracy is required in ADSB GPS or hybrid position systems. As far as I know, lat/long and GPS altitude can be obtained from an ADSB out equipped aircraft. But what accuracy do they provide? 10 meters?, 100?, 1000?.
https://en.wikipedia.org/wiki/Wide_Area_Augmentation_System A WAAS-capable receiver can give you a position accuracy of better than 3 m, 95 percent of the time.
