高精度的大气改正是加快PPP-RTK收敛的重要前提。本文以区域跟踪网台站数据为基础，基于非差非组合PPP提取斜路径电离层和天顶对流层延迟，作为PPP-RTK大气建模的数据源。电离层延迟采用基于斜路径星间单差的改正模型，对流层采用非差天顶对流层模型，设计了相关的服务端和用户端软件系统。在系统设计上，通过服务端提取数据构建大气模型并播发，用户端接收参数并用于实时PPP-RTK定位。对上海区域进行服务端...
针对轮式移动机器人的轨迹跟随问题，提出了一种基于RTK-GPS（real-time kinematic GPS）的轨迹跟随控制方法．首先，将GPS（全球定位系统）轨迹地图和机器人实时的RTK-GPS经提出的坐标转换模型转换到同一平面坐标系．因为RTK-GPS受干扰时会出现GPS点跳变，所以采用标准卡尔曼滤波器进行滤波，用最优估计值作为机器人真实的位置．通过遍历轨迹地图找寻初始最近目标点，然后不断更...
