Location tracking with Kalman Filter ,[object Object],[object Object]

Equations State vector : Measurement vector: In our case the state vector indicates, speed in <x,y> and the <x,y> Coordinates of the MH. The Measurement vector are the values of <x,y> measured from a GPS system or a location tracking device. System equations:

Equations : Matrices representing our system: Kalman Filter Time-Update equations: Q = E{ w k w k T }.

Filter Performance (MATLAB) 2-20 m Error Per Prediction T = 5 sec

Results: Average Throughput of M-IP and Predictive M-IP
