UWB Positioning Antenna Group Selection for 360-Degree Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UWB positioning systems face reduced measurement accuracy when the beacon is located on the sides or back of the anchor node due to limited positioning ranges of individual antenna groups.
Innovation Solution
The positioning communication device employs multiple positioning antenna groups with overlapping ranges, a selection switching module, and a processing module to control and determine orientation information based on received signals, ensuring accurate positioning across a 360-degree range by selectively activating antenna groups based on beacon orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single positioning antenna group is used, then the device complexity is reduced, but the positioning accuracy deteriorates when the beacon is located on sides or back of the anchor node
Solution Approach 1:
The positioning system is segmented into multiple antenna groups (first, second, third, and fourth antenna groups) with different positioning ranges. Each antenna group is responsible for specific angular sectors, allowing the system to maintain high positioning accuracy across all directions by selecting the appropriate antenna group based on beacon orientation.
Solution Approach 2:
The system dynamically selects which antenna group to use based on the beacon's orientation information. The processing module determines the beacon's angular position and activates the corresponding antenna group, making the system adaptable to different beacon positions while maintaining optimal positioning accuracy.
2Measurement precision
If multiple positioning antenna groups with different positioning ranges are used, then the positioning accuracy is improved across all angles, but the device complexity increases
Solution Approach 1:
Multiple antenna groups with different positioning ranges are merged into a single integrated system. The first, second, third, and fourth antenna groups cover different angular sectors, and their combined coverage achieves 360-degree positioning capability. The processing module coordinates all antenna groups to provide comprehensive positioning accuracy.
Solution Approach 2:
The positioning system is designed with multi-functionality to handle beacons in any angular position. Different antenna groups serve different directional ranges, and the system universally provides accurate positioning regardless of beacon location by selecting the appropriate antenna group for the current angular sector.
3Quantity of substance
If processing modules are shared among antenna groups, then hardware costs are reduced, but the switching control complexity increases
Solution Approach 1:
Processing modules are designed to be multi-functional, serving multiple antenna groups rather than being dedicated to a single antenna group. The same processing module can process signals from different antenna groups by selectively activating the appropriate group based on beacon orientation, reducing hardware quantity while maintaining positioning capability.
Solution Approach 2:
The system implements dynamic switching control where the processing module activates different antenna groups based on real-time beacon orientation. The switching is controlled by angular position thresholds, where exceeding certain angle thresholds triggers activation of the next antenna group in sequence, providing systematic control complexity management.
