observations during testing
Observations During Testing
  • The GPS points shifted from day to day and also ever so often during the day.
  • Also had to change points for different speeds due to sample rate slowing in relation to car speed.
  • Every once in a while the car would receive a bad point and correct even though it was in the center for the tunnel.
plans for next week
