◉ The GPS data will recording

equipment stop
◉ Remove several GPS data
(GPS data < IMU data)

15. Conclusions
◉ GPS data was good enough to record the point position while it had the best
performance on the crossroad and on the open area while the data was not good inside
of the building
◉ The filtered-smoothed IMU data had the best performance inside the tunnel when the
GPS data was not available and had better performance inside the building, on the
crossroad and on the open area than filtered-IMU data.
◉ Although the filtered-smoothed IMU data had better performance than filtered-IMU
data, those data still had some patches points that might be reduced by changing the
IMU parameters in the Kalman filter process.
