UbiTrack high-precision positioning system adopts the UWB (Ultra-wideband, nanosecond non-sinusoidal narrow pulses) wireless communication mode combined with multiple algorithms. Relying on the anchors that are strategically placed in the warehousing, UbiTrack displays the positioning information of people, vehicles, and things in real time on the online platform. Thanks to UWB technology and the positioning accuracy of up to 10 cm, our positioning system helps optimize the logistics operation processes in the warehousing environment, creating necessary prerequisites for efficient and targeted management of warehousing operations.
System architecture and principles
UbiTrack positioning system adopts a number of innovative data analysis and processing algorithms, and a variety of algorithms are hybrid to meet users' different positioning business needs. It has optional positioning (3D), regional positioning(2D), orbital positioning(1D) and other positioning modes.Based on the TWR and TDOA positioning algorithms, the location and surrounding environment information of personnel, vehicles and assets can be accurately located in real time. At the same time, the system also supports track playback, alarm, data interaction, camera linkage and other functions.
Single-Sided Two-Way Ranging (SS-TWR): A simple measurement of the round-trip delay of a single message from one node to node to another, and sending the response back to the original node. The error in this method of ranging increases with clock skew, and the error in the time-of-flight estimation increases to the point where the error makes the estimate very inaccurate.
Double-Sided Two-Way Ranging(DS-TWR):An extension of Single-Sided Two-Way Ranging (SS-TWR),in which two round-trip time-to-date measurements are used and combined to obtain time-of-flight. Assuming that devices A and B are 100m apart, the flight time of electromagnetic waves is 333ns. Because the clock input error is 2033310-9 seconds, resulting in a ranging error of 2.2mm, it can be ignored. Therefore, bilateral ranging is the most commonly used ranging method.
