When full accuracy GPS was released to the public under the 1990s Clinton administration, it caused a surge in the uptake of satnav by the public, from fishing boats and merchant ships, to today’s navigation using nothing but a smartphone with its built-in GPS receiver. Even so, there ...
首先利用INMARSAT的印度洋卫星作WAAS电文广播,将来利用澳大利亚自己的AUSAT卫星。返回印度的WAAS计划提出建立八个监测台发展WAAS的两步计划。首先做到能提供完好性监测和提高可用性;1 24、9982000年提高精度到满足I类精密进近着陆用,并和国际联网。返回欧洲三联体的RAAS计划欧洲全球导航重叠系统(EGNOS)计划,它是GNSS1计划...
首先大家要弄清使用GPS时常碰到的一些术语:如:坐标、航点、航线、前进方向、导向、日出日落时间等。1坐标通常人们都习惯用2维、3维这两种坐标表示,当GPS能够收到4颗及以上卫星的信号时,它能计算出本地的3微坐标:经度、纬度、高度,若只能收到3颗卫星的信号,它只能计算出2维坐标:精度和纬度,这时它可能还会显示...
