Example 6.19

There is a mobile robot that drives around on a plane and measures its position with a GPS sensor 10 times in a second (sampling time Ts = 0.1 s). The position measurement is disturbed with zero-mean Gaussian noise with variance 10 m2. The mobile robot drives with the speed of 1 m/s in the x direction and with the speed of 0 m/s in the y direction. The variance of Gaussian noise of the velocity is 0.1 m2/s2. At the beginning of observation, the mobile robot is situated in the origin x = [0, 0]T, but our initial estimate about the ...
