| 3. | In the body of this paper , we expatiated on the acquire method of gps signal and analyzed the speciality of acquire
在本文的主体部分阐述了gps信号的捕获方法，并且分析了捕获检测性能。 |
| 4. | When the signal of gps is lost for five minutes , the position error is about 1400 meters , its velocity error is about 15m / s and its attitude angle error is about 10 degree
在gps信号丢失5分钟时，位置误差大约为1400米，速度误差大约为15米/秒，姿态角误差大约为10度。 |
| 5. | By extracting the necessary information in the gps signal and merging with the satellite orbital data , the position of the radiosonde and hence the wind vector is calculated
地面站接收到gps信号后会抽出所需资料，再加入有关卫星轨道的数据，便可计算出无线电探空仪的位置，从而计算出高空风向和风速。 |
| 6. | Both the radiosonde and the ground station are equipped with special antennae for receiving satellite - based gps signals . these signals , combined with the relevant satellite orbital data , enable the wind to be computed
在探测过程中，无线电探空仪和地面站均装有特别天线，接收gps信号，再加入有关卫星轨道的数据，便可计算出高空风向和风速。 |
| 7. | Main cpu of instrument adopt digital signal process unit ( arm core ) . the hardware design adopt distributing design which separate receiving and processing gps signal from the main system to use professional gps signal from the main system to use professional dsp to fulfill
组合导航仪的主处理器采用高精简指令集( arm内核)的数字信号处理器件，硬件部分采用分布式设计，将gps信号的接收及处理独立出来，采用专用dsp进行。 |
| 8. | These analysis is based on a great deal of test . some conclusion is : geometry dilution of precision and the number of satellites can be used to pick out some abnormal points . to group the data according to the vertical dilution of precision can also pick out some abnormal points
通过对ag132大量实验和精度分析，提出了可以通过gps信号接收时的几何精度因子、卫星个数等首先剔除浙江大学博士学位论文摘要一批gps信号中的异常值，然后可以通过垂向的按几何精度因子分组判别法剔除一些异常值。 |
| 9. | Though global positioning system ( gps ) is used widely at present , it is restrained due to its intrinsic errors in existence . especially when a vehicle is running in a city canyon ( a place where high buildings are on its both sides ) or in a jam - paced place , things get more awful . in these situations , gps signals are kept out
目前广泛采用的全球定位系统( globalpositioningsystem , gps )由于本身不可避免地存在定位误差；甚至当车辆行驶在高大建筑物附近或交通拥挤的地方时，会出现gps信号受到遮挡以及多路径效应等问题，导致定位精度的下降。 |
| 10. | With the gps / avl ( gps / automatic vehivle location ) system as application background , this dissertation discussed the following issues . a . gps coordinate transformation b . to correct the wraps of gps when they are displayed on electronic map c . to make up the wraps bring by the blind spots of gps signals d . the integration technique of gps and gis and then , based on the integration of gps and gis , it presents a gps / avl systematic solution using mapx
本文以gps avl系统为应用背景，对gps坐标系与当地坐标系的变换、 gps信号在电子地图上显示时误差的校正和gps信号盲点在电子地图上显示时的弥补三个问题以及gps gis集成技术进行了研究，并给出一种利用mapx开发的基于gps gis集成的gps avl系统解决方案。 |
