【摘要】 在GPS/G IS技术支持下的导航与监控系统中,根据从卫星接收到的GPS定位信息内容,GPS接收器传送到计算机中进行信息提取和处理的方法有多种。数据采集的速度、卫星发送数据时间间隔及定位显示速度等之间有较复杂的关系。采集和传送的方法将对定位信息处理及后继导航跟踪、动态规划产生较大的影响。在实践和比较的基础上,采用W in环境下特定API函数对其加工和编程处理,完成位置解析后再通过无线通信数据链或直接经过串口传送给计算机,在实际系统运行中取得了较好的效果。更多还原

【Abstract】 In the navigation and monitoring system supported by the GPS/GIS,there are various methods to pick up and deal with the information which transmitted from the GPS receiver to the computer,according to the content of GPS orientation information received from the satellite.The speed of data collection,the time interval of TXD from the satellite and speed of location display show a complicated relationship.The method of collecting and transmitting will cause a big influence on locating information processing and successor plan of navigation and tracking.Because the API function has processed it under Win condition,we can send it to the computer by wireless communication data chain or serial port directly after finish location analyzing and the good result has been gotten in practice running.更多还原
