The BDS navigation system replaces the early-stage displacement monitoring based on GPS with the multi-system and multi-frequency mode. The complete Independence of BDS, unique constellation design and tri-frequency signals could greatly improve the accuracy of displacement monitoring in complex environments, increase reliability of system operation and reduce pre-warning time.
BDS high-precise PCB board developed by Unicore provides carrier phase’s observation accuracy of 1mm. The reliable low-elevation track and super-light observation noise helps to simplify the pre-processing of data analysis software. It is suitable to displacement monitoring application with the accuracy in the millimeter level.
