Autonomous GPS/INS navigation experiment for space transfer vehicle

Construction and performance test of a novel polarization sensor for navigation

“…Navigation information has been regarded as one of the most important information resources and the navigation sensors have been the primary component of the global information establishment. Present navigation system [2][3][4][5] is classified as: inertia navigation, radio navigation, satellite navigation and celestial navigation. A pure INS integrates several differential equations containing inertial measurements to provide a navigation solution.…”

Application of adaptive Kalman filtering algorithm in IMU/GPS integrated navigation system

“…where k X is the state parameter vector at k time; 1 k − X is the state vector at ( 1) k − time，its estimated value is…”

“…IMU/GPS, however, benefit with their own advantages, perform higher efficiency with the mutual benefit. It is well known that there are two kinds of IMU/GPS, i.e., loosely and tightly integrated systems [1,2] , the former has lower accuracy, but is simple and easy to realize.…”

Development of Steering Actuator for Unmanned Vehicle Based on Magnetic Marker

“…대표적인 방법이 카메라 (vision)를 이용한 방법으로 현재도 이 분야에 대한 연구는 활발히 진행되고 있다 [1,2]. 다른 기술로는 GPS(global positioning system)를 이용하거나 적외선(infra red) 레이더 감지센서를 이용하는 방법의 연구가 활발히 진행되고 있다 [3][4][5].…”
