单纯GPS与海上综合导航系统对比分析

GPS系统能满足定位及导航的需求，在此基础上发展起来的综合导航系统将地震勘探作业中各个系统和设备进行了软硬件的整合，可实现设备操作与同步、图形与数据的交换、工作程序控制、质量监控等多方面的综合管理。两者在功能、精度、效率上有很大的区别，通过实际施工效果的分析，证明面对一定规模的海上地震勘探作业，综合导航系统显示出更高的性能和效率。

Comparative analysis of only GPS and marine integrated navigation management system

GPS can meet the basic requirements of positioning and navigation. Integrated navigation system, which is developed on the basis of GPS,integrates the software and hardware of connected systems and equipments during marine seismic operations. With this system, integrated management is accomplished which is consist of equipment control and syn- chronization, graphics and data exchange, operation program control, QC, etc. The differences on function, precision and ef- ficiency are very apparent between GPS and integrated navigation system. By the comparative analysis of results in prac- tices, it is proved that the integrated navigation system has higher performance and efficiency when the marine seismic pros- pecting project is certain large -scale.
