摘要: 针对物探测量作业中经常会遇到密林、峡谷、窄沟等遮挡严重的不良环境,导致可视卫星数减少、卫星信号不稳定,进而造成定位结果精度下降、作业效率降低等问题。本文提出了使用多系统兼容的高灵敏度BD930板卡作为接收机主板,给出了板卡的控制方法。研制出了一款实时动态定位手簿软件,并且利用网络通信技术搭建了差分数据链,多次在实际物探测量作业环境下对整个测量系统的性能进行了测试。结果表明,该系统在一定程度上提高了RTK适应困难环境的能力,所搭建的差分数据链使测量作业更加便捷、高效,能够满足工程应用的需要。

Abstract: Geophysical survey often encounters adverse environment jungle, canyons, narrow ditch and so on. This results in the number of visible satellites reducing and unstable satellite signal. Then it causes the accuracy of the positioning results decrease, working efficiency reduce and so on. Towards this problem,the use of multi-system compatible and highly sensitive BD930 board as the receiver main board is proposed, and the control method of the board is showed. In addition,a set of real-time kinematic positioning hand-book software is developed, and the differential data chain is built through network communication technology. Tests on the performance of the whole measurement system under actual geophysical survey work environment are completed. Results show that to some extent the system improved the ability of RTK to adapt to different environments, the differential data chain built up makes the measurement operation more convenient and efficient, and the needs of engineering application can be met.

Key words: geophysical survey, multi-system compatible, BD930 board, differential data chain, RTK
