We have been carrying out solar wind measurements using the interplanetary scintillation (IPS) method. Our IPS observation system is operated at a frequency of 327MHz and consists of four stations located at Toyokawa, Fuji, Sugadaira and Kiso. The present system, however, has insufficient sensitivity to measure enough IPS sources for observing the solar wind with adequate spatial and temporal resolution. Therefore we have been excuting the upgrade project since 1994 in order to observe a larger number of compact radio sources. The Fuji system has been improved successfully and has achieved sensitivity by a factor over five compared with the previous system. The upgrade project is now in progress for the Toyokawa and Sugadaira station. 相似文献

GPS/IPS组合定位系统中的周跳检测 总被引:2,自引:0,他引:2
全球定位系统(GPS)和惯性导航系统(INS)是目前世界上最先进的导航系统。将先进的导航技术应用于精密定位,是近20年来大地测量发展的一个重要特点。本文概述了GPS和IPS(惯性定位系统)各自的优缺点;指出了研究GPS/IPS组合定位系统的必要性。提出了利用短时期IPS的结果来发现和修复GPS周跳的“比对法”。 相似文献
