Vehicle-borne tracking and position device is used to track LEO satellite. Because of the absence of the target which might be caused by cloud or zenith blind zone, the forecasting data will be used to acquire the target. While orbit prediction has serious errors, the target is always missed. Meanwhile, in its application to the vehicle-borne tracking and(More)
We introduced a design method of DSP-based System of time uniform, which combine the GPS and the Compass to calibrate the time. The system can use UTC (Coordinated Universal Time) of the GPS or the Compass for time base, to generate absolute time and different frequency of synchronous signals. We used DSP (Digital Signal Processor) to calculate the(More)
A series of CuO/Ce(1-x)Ti(x)O(2) catalysts used for low-temperature CO oxidation were prepared by impregnation with the support derived from surfactant-assisted co-precipitation. The techniques of N(2) adsorption/desorption, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and temperature-programmed reduction by H(2) (H(2)-TPR) were employed(More)
