北斗卫星技术在数字地质调查系统中的集成开发与应用

在深入了解"北斗一号"导航卫星系统技术特点的基础上，结合地质调查工作流程，研究"北斗一号"导航卫星系统与数字地质调查系统集成的关键技术和实现方式以及系统的应用推广模式。研究表明，基于"北斗一号"卫星系统与GPS的双模式位置报送机制，可以为野外地质调查人员提供稳定的位置服务；北斗终端与手机的短信互通，在无手机网络的艰险地区也可与外界保持实时沟通。基于北斗导航卫星的DGSInfo系统可实现驻地实时监控和指挥，有助于野外应急事件的快速响应和处置，在中心节点可实现全局监控，为管理部门指挥调度和决策提供依据。GSIGrid野外地质调查管理服务与安全保障系统可在固定节点实现对移动节点的移动轨迹和通讯信息实时监控，并能与野外驻地和移动目标进行互动通讯，为野外地质调查人员提供查询服务，为突发事件应急处置的管理与决策提供数据支持。集成系统在东昆仑1:50000区调项目示范应用中取得了良好效果。 

INTEGRATION AND APPLICATION OF BEIDOU SATELLITE TECHNOLOGY IN DIGITAL GEOLOGICAL SURVEY SYSTEM

On the basis of deep understanding of Beidou-1 navigation satellite system, combined with the geological survey work flow, the key technique and system application model of the integration of Beidou-1 navigation satellite system and the digital geological survey system were studied. The result shows that, based on the dual mode position report mechanism of Beidou-1 and GPS, stable position service can be supplied for the geological researcher; the interworking between Beidou-1 terminals and mobile phone short messages can be connected in remote area without mobile phone signals. The DGSInfo system based on Beidou-1 will realize real time monitoring and command at field station which contributes to the field of emergency response and disposal. GSIGrid geological survey management and safety service system will realize center node monitoring the moving path and short message of moving nodes. It can also supply information inquiry service and data support to emergency disposal and decision making. The integrated system has achieved good results in field geological survey in southwestern, northwestern and northeastern China.
