METHOD AND APPARATUS FOR INDOOR POSITIONING USING RANGING AND SENSING INFORMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18342641 titled 'METHOD AND APPARATUS FOR INDOOR POSITIONING USING RANGING AND SENSING INFORMATION
Simplified Explanation
The indoor positioning method described in the patent application involves scanning for registered Wi-Fi nodes with known coordinates, performing ranging operations with selected nodes, obtaining sensor readings from inertial measurement units (IMUs) of a device, and estimating the device's position using filtering operations.
- Scanning for registered Wi-Fi nodes with known coordinates
- Performing ranging operations with selected nodes
- Obtaining sensor readings from IMUs of a device
- Estimating the device's position using filtering operations
Potential Applications
This technology could be applied in indoor navigation systems, asset tracking in warehouses, and location-based services in shopping malls.
Problems Solved
This technology solves the problem of accurately determining the indoor position of a device without relying solely on GPS signals, which are often unreliable indoors.
Benefits
The benefits of this technology include improved indoor positioning accuracy, enhanced user experience in indoor environments, and increased efficiency in asset tracking and location-based services.
Potential Commercial Applications
One potential commercial application of this technology is in the development of indoor navigation apps for shopping centers, airports, and large indoor venues.
Possible Prior Art
Prior art in indoor positioning methods using Wi-Fi signals and sensor fusion techniques may exist, but specific examples are not provided in the patent application.
Unanswered Questions
How does this technology handle multi-floor indoor environments?
The patent application does not specify how the method accounts for multi-floor indoor environments where Wi-Fi signals and sensor readings may vary significantly between floors.
What is the power consumption of devices using this technology?
The patent application does not address the power consumption implications of implementing this indoor positioning method on mobile devices or other hardware.
Original Abstract Submitted
An indoor positioning method includes scanning for registered Wi-Fi nodes with known coordinates to generate a list of the registered Wi-Fi nodes. The method also includes performing a ranging operation by (i) selecting nodes to range with from the list of the registered Wi-Fi nodes, and (ii) processing ranging responses from the selected nodes to generate a series of distance measurements. The method further includes obtaining a series of sensor readings generated by one or more inertial measurement units (IMUs) of a device. The method also includes estimating a position of the device based on the series of distance measurements and the series of sensor readings using first and second filtering operations that are performed in parallel.
