When SINS (strap-down inertial navigation system) is combined with GPS, the observability of the course angle is weak. Although the course angle error is improved to some extent through Kalman filtering, the course angle still assumes a divergent trend

全球定位系统(Global Positioning System,GPS)是美国从20世纪70年代开始研制、历时20年、耗资200亿美元、于1994年全面建成、具有在海、陆、空进行全方位实时三维导航与定位能力的新一代卫星导航与定位系统。它是美国在子午仪卫星导
随着交通的不断发展,公路网错综复杂,定位技术应运而生。除了传统的指南针加地图,GPS定位和手机定位都是现代科技的产物。而二者的原理也有不同,因而导致二者的定位精度及反
随着汽车的日益普及,人们的活动范围已经远远超出自己熟悉的小圈子。不知道目的地在哪里,知道目的地在哪里之后又不知道走哪条路,出门在外常常会遇到这样的问题,而GPS导航仪恰恰能帮助您解决这个问题。
GPS导航器PC World中国实验室在繁忙的都市中工作和生活,压力自然不小。尽管现在很多白领都有车代步,但很多时候,这自驾的烦恼也未必少。特别是在像"北、上、广"这样的大城市,路网建设整天变,十分复杂,这时候,谁又不想带台既可带路又能休闲的GPS导航助手呢?
说起GPS导航的确已经不再新鲜了,毕竟市面上各式各样的GPS导航产品早已为人们所熟识。本刊的《走近GPS的日子》专栏也已经连续10期向大家介绍过了各种GPS产品、技术与应用信息。不过,你知道最新的时尚导航又该怎么玩么?
看过好莱坞电影《异形》的朋友相信对影片中的异形入侵还心有余悸。其实"入侵"这样的情形在现实中正在进行,一直以技术先锋示人的汽车,正在被发展迅速的IT数码以及多媒体技术快速"入侵"中……
The potential field determined based on the fictitious compress recovery approach is influenced by the errors contained in the boundary (the Earth’s surface or the surface corresponding to the satelli
The cross-coupling corrections for the LaCoste & Romberg airborne gravimeter are computed as a linear combination of 5 so-called cross-coupling monitors. The weight factors (coefficients) determined f
The principle and method for solving three types of satellite gravity gradient boundary value problems by least-squares are discussed in detail. Also, kernel function expressions of the least-squares
Three transformation models (Bursa-Wolf, Molodensky, and WTUSM) are generally used between two data systems transformation. The linear models are used when the rotation angles are small; however, when
