The description , organization and management of navigation digital map route data are the key techniques in navigation system design 摘要導(dǎo)航電子地圖路網(wǎng)數(shù)據(jù)的描述,組織和管理是移動(dòng)導(dǎo)航系統(tǒng)的設(shè)計(jì)中涉及的關(guān)鍵問(wèn)題。
As vital integral part of the laser gyro navigation system design , the study in the paper solved technical problems such as outcome distortion or even system failure resulted from bad dynamic performance of bracket and isolation device structure 通過(guò)本文的研究,成功解決了激光陀螺儀定位系統(tǒng)工作中,因支架與隔振裝置結(jié)構(gòu)動(dòng)態(tài)性能差而出現(xiàn)的結(jié)果失真及至死機(jī)的技術(shù)問(wèn)題。
Simulation results indicate this method is simple , effective and suitable for high accuracy relative navigation of lunar rover . and according to simulation , obtain relations between measuring accuracy and the number , and provide a basis for the navigation system design 仿真結(jié)果表明利用卡爾曼濾波對(duì)月球車的位置、姿態(tài)進(jìn)行估計(jì)的這種方法能夠提供較為精確的相對(duì)位姿信息;并且依據(jù)仿真結(jié)果給出了定位精度與特征光點(diǎn)數(shù)目、位置的關(guān)系,為導(dǎo)航系統(tǒng)設(shè)計(jì)提供了依據(jù)。
Secondly , the dissertation also researches the hardware composing of the system , involving the operational principle and technic guide line of superstar gps receiver , gsm - jd1 modem and rs - 232 serial port . based on the research , the gps location data transmitting software and the monitor center software of the gsm based gps vehicle location and navigation system designed in this article , is designed by the computer communication technology , serial communication technique and vc + + 7 . 0 integrated developing environment , and the system with its constitute parts are realized 在對(duì)文中設(shè)計(jì)的基于gsm的gps車輛定位導(dǎo)航系統(tǒng)中采取的superstargps接收機(jī)、 gsm - jd1調(diào)制解調(diào)模塊和rs - 232串行接口等硬件的原理和技術(shù)指標(biāo)進(jìn)行深入研究的基礎(chǔ)上,利用計(jì)算機(jī)通信技術(shù)、串行通信技術(shù)、 gsm短消息數(shù)據(jù)傳輸技術(shù)以及vc + + 7 . 0集成開(kāi)發(fā)環(huán)境設(shè)計(jì)出了系統(tǒng)的車輛定位數(shù)據(jù)發(fā)送軟件包和車輛監(jiān)控軟件包,實(shí)現(xiàn)了系統(tǒng)及其各組成部分的功能。
