Embodiment Construction

[0030] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0031] In the prior art, technicians found that: in the baseline calculation, the observation data is imported, the baseline calculation is set, the baseline calculation is performed, and a baseline calculation list is formed. The baseline solution list displays the solution status of each single baseline (floating point solution, fixed solution, unsolved, etc.), Ratio value (the error ratio between the suboptimal solution and the optimal solution), RMS (root mean square error), etc. Solving indicators. If the solution status is a floating-point solution, it can be basically judged that the baseline solution is unqualified; but even if the solution status is displayed as a fixed solution, technicians or users still cannot fully determine whether the quality of the baseline solution is qualified, for example...

Abstract

The invention relates to a method for quickly judging the quality of baseline solution, comprising the following steps: baseline solution, forming a baseline network and a baseline solution list; forming a closed loop, displaying a closed loop difference list; performing network adjustment, and passing the adjustment result to judge whether the network adjustment exceeds the limit; if the network adjustment does not exceed the limit, then end the process; if the network adjustment exceeds the limit, select the suspicious baseline according to the baseline solution list; judge whether the closed loop formed by the suspicious baseline is qualified, And according to the judgment result, a graphic mark is made for each closed loop that the suspicious baseline participates in forming, and finally the calculation result of the suspicious baseline is finally judged according to the graphic mark.

Description

technical field [0001] The invention relates to the technical field of global satellite navigation and positioning, in particular to a method for quickly judging the quality of baseline solution. Background technique [0002] At present, the static measurement application of the GNSS (Global Navigation Satellite System, global satellite navigation system) receiver is more and more extensive. However, in the prior art, at least one of the following problems exists: [0003] After the GNSS receiver receives the observation data, it will perform baseline calculation (baseline calculation: in the synchronous observation of multiple GNSS receivers, the GNSS observation data of two receivers are selected each time to calculate the corresponding baseline vector), and then According to Delaunay triangulation or other criteria, form a baseline network that can cover all stations, search for three or more end-to-end baselines to form a connected closed loop, check the closed loop, an...
