基于车载三维信息采集系统的GPS数据获取研究

Research on The Collection of GPS Data Based on Vehicle-Borne 3D-Information Data Acquisition System

文章描述了车载三维信息采集系统GPS获取定位数据的工作模式及系统主机通过VC++中的通讯控件(MSComm控件)从NovAtelGPS接收机获取定位数据的过程,并且对所获取的数据进行分析.通过实验数据分析表明,此方法在卫星信号不丢失的情况下能够保证三维信息采集系统的定位要求.

In the paper, we described the model of collecting data by GPS in Vehicle-Borne 3D-Information Data Acquisition System. Using communications component of VC ＋ ＋ , we succeeded in collecting the data from the receiver of NovAtel GPS. Through analysis of the data, we draw a conclusion that the method of data collection ensoures the position of the system under the situation that the artificial satellite signal can be received.
