HI, now i want to get the speed graph and acceleration graph of the car , which one should I choose in analyze of QGC? THANKS.
For speed there are two options:
- GLOBAL_POSITION_INT.vx and .vy but you would need to sqrt(sq(vx)+sq(vy)) to get the total velocity in cm/s
- GPS_RAW_INT.vel shows the ground speed in cm/s taken directly from the GPS (i.e. not from the more accurate EKF)
For acceleration I think you need to look at the raw sensor values:
hope this helps
