with the development of satellite navigation communication,antenna is a very important unit,performance of the satellite navigation communication system is affected by it partly.a new type of bifilar helix for satellite navigation communication system is introduced,and the traving-wave bifilar helix is analyzed briefly.meanwhile,the design and the test results are given.the results show that the antenna possesses excellent circular hemispherical beam with wide angle circular polarization and better impedance match,and has a compact structure and high integration.it can be applied in caps systems successful.

小 摘要：随着卫星导航通信技术的迅速发展，天线作为卫星导航通信系统中的重要部分，在一定程度上决定着卫星导航通信系统的性能。介绍一种用于卫星导航通信系统的双臂螺旋天线，讲述爬行波式螺旋天线的设计过程，并给出最终测试结果。结果表明，该天线具有优良的圆对称半球波束，良好的广角圆极化特性和优良的阻抗匹配特性，其结构简单、紧凑，为通信入站回传提供了一种优良的选择。

To advertisement reveal an individual to feel 768 15 is below dominant boat had better, additional the GG of home page or what MM cannot put is too much, the individual thinks 3 it is OK to go to 4, the key word of best and different home page increases special number cannot too much, actually individual of key word density thinks is gally you what you should do only is unashamed, caller can experience the station that won't be fed up with you at a draught at least Baidu of course test you also won't give K at a draught to the article publish the result OK and advanced face adds corresponding navigation column to also need not add article title cannot too similar.

对于广告位的展示个人觉得768 15在主导航下面为好，另外首页的GG或者MM不能放的太多，个人认为3到4个就可以，最好不同首页的关键字加上特殊标记不能太多，其实关键字密度个人认为就是吓唬你你只要做的问心无愧，访客能体验到至少不会一下子讨厌你的站吧百度当然考验你也不会一下子就把你给K 对于文章的发表效果可以在前面加上相应的导航栏目也可以不加文章标题不可太相似。

In this paper,we introduce the main research content and the basic principle of GAN,the situation and development of the gravity sensor ,digital map processing and matching theory in home and abroad,especially the architecture and the research results of Gradiometer As an External Navigation Aid,Gravity Aided Inertial Navigation System.

The scenarios are endless, and it's no wonder that AI developers give pathfinding tremendous attention.

游戏关卡是无穷无尽的，难怪游戏AI的开发者给导航技术这么大的关注。

That is: According to the guide star flag, the number of stars identified and the cost-function of two attitude determination algorithm to carry on the final attitude determination, the better attitude are chose as the output.Through Monte-carol simulation, the error of four cases of attitude determination algorithms is studied.

对于实拍星图，基于导航星选取过程中赋予的恒星标识及星图识别结果给出了姿态确定算法的选取原则，即：根据导航星的恒星标识、识别出的恒星数目及不同定姿算法计算出的最小代价函数值的优劣进行最终姿态计算结果的选择输出。

When the number of high accuracy guide stars identified is large, the QUEST algorithm has obvious superiority.According to night-sky observation, based on the guide star flag and the star- Identification information, the selection principle of attitude determination algorithm are given.

四姿态确定算法进行了改进的TRIAD算法和QUEST算法的探讨，这两种定姿算法各有千秋，在识别出的高精度导航星只有2颗的情况下，QUEST算法无法给出姿态，而改进的TRIAD算法可以进行三轴姿态的反演；但在识别出的高精度导航星多的条件下QUEST算法有明显的优势。

Computer numeric simulation and halfˉstuff simulatio n were put on control system.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
