Background Navigation systems for aircrafts and
spacecrafts Best accuracy But, expensive
A new navigation system Good accuracy and Inexpensive For widespread-use

Conclusion & Future work
A new INS/GPS system Using MEMS sensors and quaternion
based Kalman filters Low cost and Good performance
Future work Try other methods (ex. to change filter)
