This paper proposes a new guidance law, which considers the Field of View (FOV) of the seeker when a missile has a strapdown seeker mounted instead of a gimbal seeker. When a strapdown seeker, which has a narrow FOV, is used for tracking a target, th

A non-conservative robust Kalman filter (NCRKF) is applied to flight data to identify the aerodynamic derivatives of an unmanned autonomous vehicle (UAV). The NCRKF is formulated using UAV lateral motion data and then compared with results from the c

As a supplement to the Global Positioning System (GPS) in an urban center and indoor environment, the digital television (DTV) segment sync signal can be employed to obtain a mobile user’s position. Two DTV receivers and a counter are integrated to

In this letter, we propose an optimal finite impulse response (FIR) filter with fading memory for a class of continuous-time state space models. The proposed optimal FIR filter with fading memory is linear with respect to outputs on the recent finite

The well-known conventional Kalman filter gives the optimal solution but to do so, it requires an accurate system model and exact stochastic information. However, in a number of practical situations, the system model and the stochastic information ar

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 GP

For fault-tolerant real-time filtering, an efficient two-filter architecture is proposed. In the two-filter architecture, a host filter is operated permanently. A compression filter (CF) is intermittently initialized and operated during prescribed ti

This paper presents a new design approach of the automatic gain control (AGC) loop in driving mode of MEMS gyroscopes. The designed control loop suggests that the system can maintain constant velocity output under variations of mechanical parameters.

Recently, the adaptive two-stage Kalman filter, which can track unknown random bias, was proposed. This filter can be used for systems with unknown random bias on the assumption that the stochastic information of a random bias is incomplete. This pap
