Field Test 1

The first actual field test held on a parking lot in the campus.
This picture shows the result of GPS navigation.
The length of each small segment is approximately 6~7 meters or 20 ft.
Navigation start from the one edge of the parking lot and finish at one of the slots.

So far, there was no problem at least going from east to west or vise versa, or to the south.
However, going to the north has some problem due to heading confusion at near 360 or 0 degree which both stands for absolute North.
