电离层

Detection the Ambiguity slip is key factor for position or attitude estimation of high dynamic SAR satellite using GPS. The ambiguity slip successfully can be detected by ionosphere remanet error of dual frequency.

周跳的检测是高动态卫星利用GPS系统进行定位或姿态测量的关键因素，利用双频电离层残差可以有效地实现周跳检测。

During quiet time and substorm process, tailward flow often explored in the nearEarth magnetotail by TC1 satellite.

在磁静和亚暴期间，TC1卫星在近地磁尾，包括晨昏两侧和夜侧的尾瓣、等离子体片边界层和等离子体片区域都观测到大量来自电离层的尾向流事件。

The tailward flow tends to move from the duskside and dawnside to the nightside, and becomes stronger while moving away the Earth. From 1, Jul. 2004 to 31, Nov. 2004, TC1 satellite explored 516 tailward flow events between 7RE to 13RE, which the duration exceed 3 min.

与来自中磁尾的地向流相比，近地磁尾近赤道区域来自电离层的尾向流具有低温高密特性。2004年7月1日至2004年10月31日期间TC1卫星在近地磁尾（7RE～13RE之间，RE为地球半径）观测到持续时间超过3 min的尾向流共516起。

The test results show that the proposed method can effectively compensate even for rapid TID and has good adaptability for different ionospheric frequency modulations.

测试结果表明，该方法能有效地补偿快速的TID污染，并且对不同电离层频率调制具有良好的自适应性。

The reconnection voltage is approximately fitted by sin~(3/2)θ_(IMF/2 for its response toθ_.The ionospheric transpolar potential and the voltage along the polar cap boundary show different depondencies from that of the reconnection voltage,so it is not justified to take them as substitutes for the reconnection voltage in measuring the total reconnection rate.

2重联电压与θ_之间近似满足sinθ_(IMF/2~(3/2)关系；电离层的越级电位和极盖区边界上的电压随sinθ_(IMF/2~(3/2)的变化呈现不同的规律，一般不能简单用它们取代重联电压来量度总重联率。

VHF can also be reflected from clouds of increased ionisation in the E layer of the ionosphere.

VHF 可能并且被反射从增加的电离云彩在电离层的E 层数。

Radar altimeters selects full-deramp technology in pulse compression, and apply two frequencies to reduce the ionospheric range errors.

由于现代星载雷达高度计采用了脉冲压缩技术，引入了电离层色散误差，在双频高度计的低频段该误差更明显。

It is found that in both the polar cap and the auroral zone a F1 like peak of ionization appeared at 190km height during the main and recovery phases of the storm; while the normal F2 peak disappeared and great depletions of electron density occurred.

发现在磁暴主相和恢复相初期，极光椭圆和极盖区电离层都在大约 1 90km高度出现类似F1的峰，F2主峰完全消失，F区电子密度大幅度下降。

They experimented with the effects of "artificially induced ionospheric depletions on very low frequency wave lengths, on equatorial plasma instabilities, and on low frequency radio astronomical observations over Roberval, Quebec, Kwajelein, in the Marshall Islands and Hobart, Tasmania" Advanced Space Research, Vo1.8, No.

他们实验&在近赤道离子不稳定区域以甚低频波长人工诱导电离层损耗，或者对魁北克罗伯威尔、马绍尔群岛桂哲林和塔斯马尼亚州霍巴特的低频无线电天文观测&（《高级太空研究》，卷1.8，1号，1988）。

From the surface, the atmosphere is labelled the troposphere for the first 14km up, then the tropopause (4km height), then the stratosphere (about 32km height), then the mesosphere (40km), then the ionosphere (over 600km in height) and finally the exosphere (another 200km), which is the boundary of space.

从表面上看，气氛标签的第一个14公里的对流层上升，那么对流层顶（4公里高度），然后在平流层（约32公里高度），然后中间层（40公里），然后在电离层（高度600公里以上）和最后是散逸层（另200公里），这是空间的边界。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
