Hi everyone, im recently starting with Arduino, reading a lot, but i have some question about my project...
I need to collect data (maybe 3 times in 1 second) of Velocity and Position of one player in a soccer field. My doubt is that GPS is not so accurate for the area I need to control, theres to much error.
The error of the position can not be more than 20cm.
what do you suggest i have to use for this? how can a I reduce the error?
