摘要
地质调查与监测领域等主要业务在野外探勘和核查验证过程中,对导航和定位服务有明确的需求。为了摸清地质调查与监测领域对北斗增强服务的不同需求,评估其应用效果,面向地质矿产资源调查、矿山执法监测、地质环境调查与监测三大主体业务,全面分析了各业务对导航定位精度、服务频率、通信服务等方面的详细需求,设计了不同比例尺的业务导航定位增强产品,明确了各类增强产品的精度、服务对象、播发方式、服务范围等,为提高野外工作效率、保障野外作业安全、实现导航系统国产化提供了新的技术方法。
In the process of geological survey and monitoring,a lot of field surveys,verification and check work are required,and there are clear business requirements for navigation and positioning services.In order to popularize the application of ground-based augmentation system(GAS)in the geological field,it is first necessary to find out the different needs of GAS of BDS in the field of geological survey and monitoring.Focus-ing on the three main businesses of geological and mineral resources investigation,mine law enforcement monitoring and geological environ-ment investigation and monitoring,we comprehensively analyzed the detailed requirements of various businesses in the field of geological sur-vey for navigation and positioning accuracy,service frequency,communication services,designed different scales of navigation and positioning enhancement products,and defined the precision,service object,broadcasting means and service scope.This research can provide a new techni-cal method for improving the efficiency of field work,ensuring the safety of field work,and realizing the positioning of navigation system.
