Frontend Design for High Accurate Positioning with GPSover weak signals must be amplified without causing additional noise and in such a way as to keep the thus resulting position uncertainty at a minimum. This is the task of the low noise pre-amplifier (LNA). The most significant problems that occur in the design of a frontend will be discussed.作者: 轎車(chē) 時(shí)間: 2025-3-22 06:19

Empirical Accuracy of Positions Computed from Airborne GPS Datanes. Numerous investigations in static geodetic positioning (refs. 3, 14, 15) have meanwhile demonstrated a high accuracy potential of the GPS. Relative positioning accuracies in the order of centimetres are typical when using GPS carrier phase observations in the static mode.作者: 商業(yè)上 時(shí)間: 2025-3-22 21:27 作者: 慷慨援助 時(shí)間: 2025-3-23 04:43

Vehicle Guidance by Computer Vision road vehicle guidance is discussed. Based on the recursive, feature-based state estimation, numerically efficient situation recognition and process control has been achieved. With 0.1 second cycle time, speeds up to 60 mph have been driven autonomously over distances up to 24 km on a standard highway with the 5-ton test vehicle VaMoRs.作者: 傷心 時(shí)間: 2025-3-23 22:24
