摘要
A new geodesy technique based on multilateration is presented. A wide-angle laser ranging system has been developed and validated experimentally. A single-shot accuracy of 1 cm is achieved. A terrestrial experiment conducted with this instrument achieved a relative positioning accuracy of 1-2 mm for a linear network of ground-based retroreflectors. Results are compatible with theoretical predictions and covariance analysis. They validate both the instrument and data processing methods. The next step will be an aircraft experiment over a two-dimensional network.
