Satellites millimeter displacement monitoring has been always based on BeiDou, GPS, GLONASS which obtains a wide range of applications in domestic bridges, dams, landslides, power grids, towers, tunnels, settlement, pits, dangerous houses and other fields. It has also achieved significant economic benefits and better safety and security. Due to a variety of objective reasons, it has to achieve millimeter-level accuracy. The current domestic mainstream manufacturers basically use a static solution mode, generally need half to one hours to solve the millimeter-level accuracy of the results of the data. Especially in the case of sudden acceleration and deformation of the monitoring object such as landslide, dangerous building, bridge, settlement, etc. This solution mode has a long period of time for the results, lags behind the solution, and is unable to obtain the current displacement of the monitoring object in the first time. It is difficult to meet the needs of some specific industries.
In order to solve the industry's pain points, we made a major technological breakthrough based on the BeiDou (also compatible with GPS, GLONASS, etc.) satellite high-precision millimeter displacement rapid solution by joint professional team of Wuhan University and invested a lot of manpower and material resources and took more than a year of R&D, repeated testing, improvement and validation. Specific as follows:
1. The realization of the monitoring of the object deformation state by auto-recognition. Automatic conversion between static and dynamic solving modes according to the size of deformation of the monitoring object.
2. Realized rapid identification and stable solving in case of large amount of sudden changes in monitoring object, and to respond and quickly solve the resultant data within 20 seconds.
3. High precision, stable data, and dynamic error accuracy less than 8mm.
4. Application Validation Demonstration:
Application validation results 1: In static solving mode, high-precision BeiDou receiver has processed a large number of single mutation and the solving platform quickly identify and respond to the result within 20 seconds to solve the result data, to be deformation stabilization automatically transferred to static mode.
Application validation results 2: In the static solution mode state, high-precision BeiDou receiver carried on a large range of continuous multiple second-by-second mutation. The solution platform has quickly identifying and responding within 20 seconds to solve the results of the data. Before the deformation stabilized, the platform has been in a rapid solution state.
