1中阿40m射电望远镜选址与电磁环境监测显示文摘优良站址的选择是射电望远镜完成既定科学目标并实现高效运行的重要保障。影响射电望远镜选址的主要因素包括电磁环境、水文、气象、地质条件、隔离性与可及性等。对于射电天文观测而言,来自宇宙天体的射电信号往往极其微弱,对望远镜系统及设备的灵敏度要求极高。然而,随着人类活动的不断加强,人们日常工作和生活中使用的电子通讯设备越来越多,无线电干扰源呈爆炸式涌现。在射电望远镜选址工作中,进行电磁环境监测,选择一个电磁环境良好的站址,对于射电望远镜实现常规观测运行、获取有效数据资料至关重要。同时,电磁环境监测结果也是射电望远镜接收机系统研制、站址电磁环境及无线电宁静区立法保护的重要依据。中阿天文学者和技术人员历时1年半完成了16个候选站址的初步勘察,并对优选出的3个主要候选站址进行了深入细致的电磁环境监测工作,获得了大量可靠数据。中阿双方依据电磁环境监测结果并结合各主要候选站址的水文、气象、地质及道路等条件,最终将位于Talacasto戈壁的3号候选站址确定为中阿CART射电望远镜的建设站点。赵卫普 李建斌 李金增 孙建民 齐力 罗滔 马晓耘 莫铠玮 李鹏程 夏跃兵 MALLAMACI C C PODESTA R C PACHECO A M ACTIS E CASTRO J I ALVIS R H LOPEZ C E FRANCILE C PODESTA F PEREZ J 2014天文学进展2014,32,3:4
2Successful operation of a cooperative SLR station of China and Argentina in San Juan显示文摘We introduced the observations and researches using a Satellite Laser Ranging (SLR) system with high precision, which was designed and made in China and installed in the Observatory of San Juan Uni- versity, Argentina, the capability of the system and the achievement of the cooperative procedure be- tween China and Argentina. The SLR station in San Juan, set up by China and Argentina, is quite sig- nificant for improving the distribution of SLR stations and enhancing the orbital coverage of the whole earth. Since the SLR system started to work in the Observatory of San Juan University in the beginning of 2006, the operation is rather good, and rich data with high precision have been obtained. Further plan of the cooperation for the near future is also presented.HAN YanBen LIU WeiDong E ACTIS R PODESTA WANG TanQiang GUO TangYong QU Feng A M PACHECO A A GONZALEZ E ALONSO XIANG QingGe HUANG DongPing YIN ZhiQiang 2008Chinese Science Bulletin2008,53,16:2
