例句与造句

1. Gps signal transfer machine gps signal transfer machine
2. Chapter studies the detection and acqusition of satellite navigation signal
3. In the body of this paper , we expatiated on the acquire method of gps signal and analyzed the speciality of acquire
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
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
6. 用gps信号造句挺难的，这是一个万能造句的方法
7. 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
8. 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
9. 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
10. 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
11. 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
12. It is discussed with emphasis of developing method , software mainframe of navigation system and receiving & processing of gps signal with multi - thread technology . in addition , some technologies and implementation relating to development process of navigation system are given as well
13. Secondly , we apply tk operator to the cross - correlation of received signal code and pn code to separate the multi - paths . it comes to a conclusion that tk operator can separate the multi - paths within less than the chip period accurately of spread - spectrum system with space - modulation by simulation . at last , we apply this algorithm to the practical signal collected by gps tap , and from the result we can drop a conclusion the tk algorithm is practical
14. The results indicate that : with sa , the position precision of the integrated system , whose gyro drifting is 50 degree / hour and whose accelerator offset is 0 . 001g , is 60 meters , its velocity precision is about 1 . 75m / s out and its attitude angle precision is about 0 . 25 degree . without sa , the position precision is about 20 meters , its velocity precision is about 0 . 5m / s and its attitude angle precision is about 0 . 1 degree . when the signal of gps is lost , the growing rate of the integrated system error is much lower than that of sins system
15. Gps is a planet wireless conductance system which is global and all - weather , gps can offer high precision time orientation information to infinite user , clock precision reachs 10 ? 6 magnitude 。 not only changes traditional time method of quartz crystal clock , but also replaces wireless shortwave and even more lowfrequency signal and tv signal whose overlay range is limited and low precision , offers advantage to geology field task , achieve automatization and high precision of seismic flow observation
16. Based searching the code phase parallel and carrier frequency serially at the same time , this dissertation uses differentially coherent combining to combine the coherent result of multiple correlators to improve the snr of the received signal , so that it can acquire the weak gps signals , i . e . signals down to ? 147dbm received power
