Design of Multi Area Wireless Clock Synchronization in UWB Positioning

As an indoor high-precision positioning technology, UWB has many advantages. Its TDOA solution principle based on time difference of arrival requires extremely high clock synchronization accuracy. The wired synchronization method faces difficulties in circuit design and engineering construction, and it is not suitable for large-scale engineering applications. This paper studies the basic principles of wireless clock synchronization, extends the principle of multi area wireless clock synchronization, abstracts a simpler general processing method, and further proposes a design of multi-previous synchronous anchors, and improves system reliability. Actual test proves the method is effective.
