PK-1000 is a cm-level accurate positioning / distance measuring kit with independent intellectual property rights. It is featured with a scheduling system based on clock synchronization. This in-house developed scheduling system, combined with traditional UWB positioning technology, has enabled PK-1000 with the ability to solve the biggest problem in usual TOA (time of arrive) based UWB positioning method -- poorly configurable mesh network. This deficiency means that global positioning in a large complex environment cannot be achieved by usual UWB, while with PK-1000, it is possible. PK-1000 is suitable for research, as well as for integrating with any third-party products. For more information about this kit, please download the Introduction in Detail, then you can follow the User Manual of PK-1000, set up the kit by yourself , and make further development.
