The demand for location based services in automobile industry promoting applications in the area of telematics, vehicle to vehicle and infrastructure communications is encouraging research in the field of accurate navigation solutions. According to the ABI research, position data is the prime enabler for above mentioned applications and the in-car navigation market growth is predicted to grow at 25.9% over the next five years. Consequently position, velocity and heading form the prime input state vector for the target applications. Global Positioning System is one of the accurate off-board sensors for navigation solution. Nevertheless, the cost and complexity of these systems are posing the biggest challenge to the automobile research engineers. Least squares estimation is one of the proven methods used for computing positioning solution under static conditions. However, its accuracy is considered to be poor in dynamic cases.
