利用单频GPS代替双频GPS进行短基线变形监测的探究

如今工程建设越来越多,为保证工程质量,变形监测控制必不可少。利用单、双频GPS接收机分别对基线较短的控制网进行监测比对试验,通过对比分析监测数据进而得出结论;如果采用单频GPS接收机也可以得到较好的监测成果,满足监测精度要求,如此则可以采用成本更低、架设更为方便的单频GPS接收机代替价格昂贵、操作复杂的双频GPS接收机,极具实用意义。

Study of Using Single-frequency GPS instead of Double-frequency GPS in Short Baseline Deformation Monitoring

Nowadays deformation monitoring control is essential to ensure more and more projects quality.Intercomparison measurement of single-frequency and dual-frequency GPS receiver respectively in short baseline control network is conducted.Conclusion has been reached by comparing monitoring data.If operators adopt the single-frequency GPS receiver can also get a better monitoring results to meet the monitoring accuracy requirements,they can erect a more convenient single-frequency GPS receiver by lower costs,instead of expensive and complicated dual-frequency GPS receiver.It has practical significance.
