| 中文摘要: |
| 2019年可能由于GPS卫星滚周不同、日期格式等参数变化，以往正常使用的LEMI-417M型长周期大地电磁测深仪器突然出现了无法锁定GPS卫星的问题，对正在开展的野外工作造成了重大困扰。考虑到项目周期、工区气候、道路状况以及经费成本等综合因素的制约，在对该仪器数据采集工作方式、二进制数据结构剖析的基础上，提出了一套针对GPS失锁问题的软件应急解决方案并开发了一套具有较高实用价值的软件工具，值得在行业内推广使用。 |
| 英文摘要: |
| In 2019, due to the parameter changes of GPS satellite, such as different roll circumference and date format, the lemi-417m long period magnetotelluric sounding instrument, which was normally used in the past, suddenly appeared the problem that GPS satellite could not be locked, which caused great trouble to the ongoing field work. Considering the constraints of project cycle, work area climate, road conditions and cost of funds, based on the analysis of data collection principle and binary data structure of the instrument, a set of software emergency solution for GPS lock loss is proposed and a set of software tool with high utility value is developed, which is worth to be popularized and used in the industry of deep geophysical survey. |
