- 15. The reason for putting those values in, and try again this test to reduce errors 1. 0.06 = (data term of vision team) 2. The smaller error covariance, the better, because measured at short intervals *The larger the Q, the more the measured value is affected and the more volatile the estimate is obtained. *The larger the R, the less the measured value is affected and the change gets a mild estimate 3 Test Program and Results Application Test these files and compare this data to Kalman data Test this system model, this is initial data. This is final system model. 15
