【Abstract】 The basic idea of intelligent transport systems(ITS) is introduced in this paper. GPS/INU/DM integrated navigation & location technology and its application in ITS are described. In addition, several technical measures to increase integrated navigation & location precision and reliability are presented. This technology combines satellite navigation, inertial navigation with information technologies, and has all direction, 24 hours standby and non shadowed characteristics. The ‘automation’ of transportation management and the ‘intelligence’ of vehicular driving will be realized through using of integrated navigation & location technology. Integrated navigation & location technology has better practicing value and widely prospect.更多还原
