  Hi I like to integrate GPS and INS using kalman filter to predict the position of a vehicle. first of all i like to use GPS sensor readings with kalman filter . I have read lot of research papers for that purpose but I donot know how to use real time data of GPS sensor in the kalman filter measurement equation. My question is that where i have to put the readings the gps sensor in measurement equation i.e where to put numerical values the sensor in the measurement equation.how these values make sense. zk=Hxk+wk also i like to ask as how can i determine the state transition matrix F and observation matrix H for a particular application. also how can i determine the measrement noise matrix the gps sensor. thanks and regards
