摘要

太空天气在今天的科学中是一个相当新的领域,对人类和一般技术有着非常有趣的影响。地磁风暴是空间天气和日地联系的一部分。这些风暴极大地影响了地球的大气层和电离层。这个项目的重点是在地磁风暴期间检测tid。TID是由太阳活动引起的电离层扰动的一部分。本项目中重要的参数是TEC,即TEC变化率的值;DeltaTEC在15分钟内测量,以检测TID。TEC是使用GPS双频数据提取的,该数据采用RINEX格式,由JUPEM(马来西亚调查和地图部门)提供,并从位于柔佛州马来西亚科技大学的接收站(纬度(E) 103.60,经度(N) 1.60)获取。DeltaTEC的值根据不同七天的最大日Kp指数进行比较。

Determination of traveling ionospheric disturbances of geomagnetic storm by using dual frequency GPS data
Space weather is a fairly new field in science today and has very interesting effects on the humans and technology in general. Geomagnetic storms are part of space weather and the solar-terrestrial connection. These storms have greatly affected the earth' s atmosphere and ionosphere. This project focus on detection of TIDs during geomagnetic storms. TID is part of disturbance that occurs at ionosphere and it is caused by sun activities. The important parameter in this project is TEC which is the value of TEC change rate; DeltaTEC is taken within the period of 15 minutes in order to detect TID. TEC is extracted using GPS dual frequency data which in RINEX format that supplied by JUPEM (Department Of Survey and Mapping Malaysia) and taken from receiver station located at Universiti Teknologi Malaysia, Johor (Latitude (E) 103.60 Longitude (N) 1.60). The value of DeltaTEC is compared base on largest daily Kp index for different seven days.
