The real roll pitch can be measured with MS-3 magnetometer and GPS receiver.The algorithm of magnetic deviation compensation is presented
which is based on ellipse hypothesis.A set of data collection and magnetic deviation analysis experiments which can simulate different magnetic disturbances are designed.The data is presented by using effective arithmetic based on the help of GPS.The experimental result indicates the error about magnetometers is reduced to less than 0.6° after compensation.
