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.
