Dual quaternion is the parameter that can describe position and attitude in a unified form. It is extension of dual number and quaternion; so, mathematical and parameter characteristics of those are holding. The attitude and orbital kinematics model can be concurrently integrated in a simplified and intuitive formulation with dual quaternion. From these merits, dual quaternion-based relative navigation...
This paper deals with the critical arithmetic analysis of the Attitude Determination System design of Nano-satellites considering the sensor combination model considering finely-selected MEMS based Gyroscopes, Magnetometers and Sun Sensors respectively. Though the competency for achieving higher accuracy for proper positioning of a Nano-satellite is being experimented across the globe effectively,...
This paper studies a terrain referenced navigation which estimates a status of aircraft by using terrain elevation database and radar altimeter measurements. Terrain referenced navigation algorithm usually divides into two modes which are acquisition mode and tracking mode. In the tracking mode, states are estimated in real-time and extended Kalman filter(EKF) is a well-known navigation method for...
