Abstract
A smart munition revolves by 2~3Hz when it flights. Before guidance starts, the roll estimation of
a smart munition is an important factor to improve the navigation performance. The roll estimation algorithm
is already known using IMU and GPS. But GPS cant be available as a measurement under GPS jamming
environment. This paper explains how to estimate the roll angle of a smart munition under jamming
environment by using IMU, earth magnetism measurements. The system and measurement models of the
extended Kalman filter are designed for GPS jamming environment. Under GPS jamming environment, the
proposed method shows better performance than the previous method by Monte Carlo simulation.
