ROBUST INDOOR POSITIONING SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18345761 titled 'ROBUST INDOOR POSITIONING SYSTEMS
Simplified Explanation
The abstract describes a method for robust indoor positioning systems. It involves receiving signals from multiple anchors, which are used to identify the distance between a tag and each anchor. The method then determines multiple anchor sets from the received signals. For each anchor set, a preliminary tag location is determined based on the tag distances corresponding to the anchors in the set. Finally, a final tag location is determined based on the preliminary tag locations.
- The method involves receiving signals from multiple anchors.
- The signals are used to identify the distance between a tag and each anchor.
- Multiple anchor sets are determined from the received signals.
- For each anchor set, a preliminary tag location is determined based on the tag distances corresponding to the anchors in the set.
- A final tag location is determined based on the preliminary tag locations.
Potential applications of this technology:
- Indoor navigation systems: The robust indoor positioning system can be used to accurately track the location of individuals or objects within indoor environments, enabling efficient navigation.
- Asset tracking: The method can be applied to track the location of assets within indoor spaces, such as warehouses or hospitals, improving inventory management and asset utilization.
- Security systems: The technology can be integrated into security systems to monitor the movement of individuals or objects within a building, enhancing security measures.
Problems solved by this technology:
- Inaccurate indoor positioning: The method addresses the challenge of accurately determining the location of tags within indoor environments, where GPS signals may not be available or reliable.
- Signal interference: The method robustly handles signal interference or obstacles within the indoor environment, ensuring accurate positioning even in challenging conditions.
- Scalability: The technology allows for the use of multiple anchors and anchor sets, enabling scalability and flexibility in indoor positioning systems.
Benefits of this technology:
- Accurate indoor positioning: The method provides a robust and accurate solution for indoor positioning, improving the overall user experience and enabling various applications.
- Flexibility and scalability: The use of multiple anchors and anchor sets allows for flexibility in system design and scalability to accommodate different indoor environments.
- Robustness to signal interference: The technology can handle signal interference or obstacles, ensuring reliable positioning even in complex indoor environments.
Original Abstract Submitted
A method for robust indoor positioning systems includes receiving, from each of a plurality of anchors, a signal based on which a tag distance corresponding to a distance of a tag from the respective anchor is identified, and determining a plurality of anchor sets from the plurality of anchors. The method further includes, for each of the anchor sets, determining, based on the tag distances corresponding to anchors in the anchor set, a preliminary tag location corresponding to the respective anchor set; and determining a final tag location based on the preliminary tag locations.
