The transmission link of CAPS navigation and communication system

Science China(Physics,Mechanics & Astronomy) 2009年第3期52卷 402-411页

The Chinese Area Positioning System (CAPS) is based on communication satellites with integrated capability, which is different from the Global Positioning System (GPS), the International Maritime Satellite Organization (Inmarsat) and so on. CAPS works at C-band, and its navigation information is not directly generated from the satellite, but from the master control station on the ground and transmitted to users via the satellite. The slightly inclined geostationary-satellite orbit (SIGSO) satellites are adopted in CAPS. All of these increase the difficulty in the design of the system and terminals. In this paper, the authors study the CAPS configuration parameters of the navigation master control station, information transmission capability, and the selection of the antenna aperture of the communication center station, as well as the impact of satellite parameters on the whole communication system from the perspective of the transmission link budget. The conclusion of availability of the CAPS navigation system is achieved. The results show that the CAPS inbound communication system forms a new low-data-rate satellite communication system, which can accommodate mass communication terminals with the transmission rate of no more than 1 kbps for every terminal. The communication center station should be configured with a large-aperture antenna (about 10-15 m); spread spectrum com- munication technology should be used with the spreading gain as high as about 40 dB; reduction of the satellite transponder gain attenuation is beneficial to improving the signal-to-noise ratio of the system, with the attenuation value of 0 or 2 dB as the best choice. The fact that the CAPS navigation system has been checked and accepted by the experts and the operation is stable till now clarifies the rationality of the analysis results. The fact that a variety of experiments and applications of the satellite communication system designed according to the findings in this paper have been succ

先天免疫是宿主识别病原及消除病原感染的第一道防线。模式识别受体是参与识别病原入侵的主要分子，主要包括Toll样受体、RIG-I样受体、NOD样受体和C型凝集素受体等。模式识别受体在识别病原相关分子模式后，激活机体的先天免疫信号通路，诱导炎症细胞因子和干扰素的产生，从而启动抵抗病原入侵的免疫应答。越来越多的证据表明，免疫应答的激活、维持和终止受到了严格的调节，使机体在保持一定免疫强度的同时避免产生过度的免疫反应。microRNA是一类长度为18～23 nt的微小非编码RNA，是鱼类先天免疫应答网络中的重要调控因子。近年来，microRNA在鱼类免疫学领域已开展了大量的研究，但缺乏对其进行及时地全面性的总结。本文综述了近年来miRNA在鱼类先天免疫反应中的研究进展，以期为鱼类的分子抗病育种及疾病防控研究提供一些思路。
