- Abstract : the attitude error performance of electrostatic gyro should be understood and the relevant error equations must be set up in order to ensure the navigation precision of esgm . the relation between the navigation errors and the attitude errors of gyro was derived by use of spherical triangle . the simulation results show that the temporal performances of the longitudinal and distance errors which come from the initial alignment errors are periodically variational . they also show that the longitudinal and distance errors resulted from gyro drifts are not convergent in time . thus , the effects of initial alignment errors and gyro drifts can not be neglected and must be estimated and compensated
文摘:為了保證靜電監(jiān)控器的導(dǎo)航定位精度，需要了解靜電陀螺的姿態(tài)誤差特性，建立相應(yīng)的誤差方程.本文采用球面三角形原理推導(dǎo)了導(dǎo)航定位誤差與陀螺姿態(tài)誤差的關(guān)系式.仿真結(jié)果表明，由初始定向誤差引起的經(jīng)度誤差和距離誤差的時(shí)間特性是周期變化的；由陀螺漂移引起的經(jīng)度誤差和距離誤差是隨時(shí)間發(fā)散的.因此，初始定向誤差和陀螺漂移的影響不能忽略，必須對(duì)其進(jìn)行估計(jì)和補(bǔ)償 - Compared with currently fire control system , apsse has such characteristic as : highly precision , complex construction , high technique , etc . so this thesis expatiated in detail on the measuring theory of apsse , emphases on the discussion of system error and random error of apsse , deduced the three axis error of apsse usign the coordination transformation methods , provided the applying base for the measuring error equation of apsse . in this paper , we emphases on expatiating the basic theory of usign space coordination transformation in the measuring error equation of apsse
因此，論文采用了空間坐標(biāo)變換方法分析機(jī)載光電跟蹤測(cè)量設(shè)備在對(duì)目標(biāo)進(jìn)行測(cè)量、定位時(shí)空間坐標(biāo)轉(zhuǎn)換關(guān)系，推導(dǎo)出從中心地平坐標(biāo)系到目標(biāo)坐標(biāo)系的變換矩陣，在此基礎(chǔ)上首先建立機(jī)載光電跟蹤測(cè)量設(shè)備的無測(cè)量誤差的位置傳遞方程和機(jī)載光電跟蹤測(cè)量設(shè)備的含有測(cè)量誤差的位置傳遞方程，為利用蒙特卡洛法分析機(jī)載光電跟蹤測(cè)量設(shè)備的測(cè)量誤差奠定了理論基礎(chǔ)。 - Because the ins error equation is unstable , some initial states error will cause error floating and error accumulating , if the filter observations were only position error , kalman filter will converge very slowly , and some states error ( such as yaw error ) will be great . since the milemeter altimeter and piloting could only output position information , this paper put forward a method , firstly estimateing states and then kalman filtering , to improve filtering effect . simulation proved that this method could effectively reduce the system states error , quicken filtering convergence and improve filtering precision
由于慣導(dǎo)系統(tǒng)( lsins )的誤差方程是發(fā)散的，某些初始狀態(tài)的誤差會(huì)引起誤差的漂移和積累，當(dāng)觀測(cè)量只有位置誤差時(shí)，卡爾曼濾波的收斂速度很慢，某些狀態(tài)(如方位角)誤差很大，而以上除慣導(dǎo)外的其它導(dǎo)航傳感器直接提供的只是位置信息，為了改善濾波器性能，本文根據(jù)里程計(jì)等傳感器的特點(diǎn)，提出了首先對(duì)狀態(tài)做出估計(jì)，然后在狀態(tài)估計(jì)的基礎(chǔ)上，進(jìn)行卡爾曼濾波的方法。 - Including usign coordinate transformation method to deduce the uniform coordinate from the object coordinate to the photo coordinate , then setup the measuring error equation of apsse , this established the theory ground of usign the mont carlo method to analysis the error of apsse . there are errors from every tache of coordinate transform
由于建立機(jī)載光電跟蹤測(cè)量設(shè)備的測(cè)量誤差的位置傳遞方程是基于空間坐標(biāo)變換的基礎(chǔ)上，從中心地平坐標(biāo)系到目標(biāo)坐標(biāo)系的變換涉及到幾十個(gè)環(huán)節(jié)，而每個(gè)環(huán)節(jié)都有誤差，其誤差的性質(zhì)和大小直接影響對(duì)目標(biāo)的定位測(cè)量。 - It's difficult to find error equation in a sentence. 用error equation造句挺難的
