查询词典 ionosphere

This research process the ionosphere-free triple-differenced carrier phase observation which consist of double frequency GPS observations from the GPS receiver carried on the CHAMP and 40 IGS tracking stations. Besides, the tropospheric correction model, solid earth tide correction, mass center correction of the satellite, earth rotation correction and antenna phase center correction are incorporated. Finally, determine the satellite short-arc orbit with the pure geometry, kinematic, method.

Ionosphere is a non-linear response system. Different kinds of input will trigger different final perturbations.

电离层是一个非线性响应系统，不同触发因素作用后生成的输出扰动不同，因此对电波传播的影响也不同。

Several usual models for troposphere delay and ionosphere delay are discussed and their influences to different time transfer methods are analyzed.

本文讨论了几种常用的对流层延迟和电离层延迟模型，分析了它们对各种时间比对方法的影响。

Consequently, the vertical TEC around the receiving station was exported. Through this method, the vertical TEC got is an average value of a prick angle around the vertex. With the statistics of dispersion and the high precision data collected in Kunming station, the authors calculated the day by day time sequence value of total electron content in altiplano zone ionosphere. Based on this, they described the characteristics of TEC Sunday-changing in double-hump zone, comparing with CORS of Kunming.

这种方法得到的垂直TEC为天顶周围一锥角内的平均值，通过离散度的统计，并结合昆明站采集得到的高精度数据计算了该地区电离层2007年6~8月的电离层电子浓度总含量的逐日时间序列值，在此基础上对照昆明市连续运行参考站CORS描绘出了对于处在双驼峰区里该地区TEC日变化的特性。

Similar experiments, but using Chemical Release Modules, have been launched from Churchill, Manitoba. In 1980, Brian Whelan's "Project Waterhole" disrupted an aurora borealis, bringing it to a temporary halt. In February 1983, the chemical released into the ionosphere caused an aurora borealis over Churchill. In March 1989, two Black Brant X's and two Nike Orion rockets were launched over Canada, releasing barium at high altitudes and creating artificial clouds.
