AUTOMATICALLY CALIBRATING ANCHOR DEVICES IN AN INDOOR POSITIONING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17638002 titled 'AUTOMATICALLY CALIBRATING ANCHOR DEVICES IN AN INDOOR POSITIONING SYSTEM

Simplified Explanation

The abstract describes a patent application for an indoor positioning system using ultra-wideband (UWB) anchor devices to determine the locations of these devices and ultimately the location of a client device within the system.

  • The indoor positioning system obtains distance measurements between each pair of UWB anchor devices based on round trip time of UWB signals.
  • The system determines the location of each UWB anchor device within the system using the distance measurements.
  • An absolute network topology of the UWB anchor devices is reconstructed using their determined locations.
  • The absolute network topology is used to determine the location of a client device within the indoor positioning system.

Potential Applications

This technology can be applied in various industries such as:

  • Indoor navigation systems for large buildings like shopping malls or airports.
  • Asset tracking in warehouses or manufacturing facilities.
  • Location-based services for museums or exhibitions.

Problems Solved

  • Accurate indoor positioning without relying on GPS signals.
  • Efficient tracking and monitoring of assets or personnel in indoor environments.

Benefits

  • Improved safety and security with precise location tracking.
  • Enhanced customer experience through personalized location-based services.
  • Increased operational efficiency in various industries.

Potential Commercial Applications

Optimizing Indoor Navigation Systems with UWB Anchor Devices

Possible Prior Art

Prior art in indoor positioning systems using different technologies such as Bluetooth or Wi-Fi signals for location tracking.

Unanswered Questions

How does the system handle interference in indoor environments that may affect the accuracy of distance measurements?

The system may utilize algorithms to filter out noise and interference, but the specific methods are not detailed in the abstract.

What is the scalability of this indoor positioning system in terms of the number of UWB anchor devices that can be deployed?

The abstract does not mention the limitations or scalability of the system in terms of the number of UWB anchor devices that can be used simultaneously.


Original Abstract Submitted

To determine locations of ultra-wideband (UWB) anchor devices in an indoor positioning system, the indoor positioning system obtains distance measurements between each pair of N UWB anchor devices in the indoor positioning system. Each distance measurement is determined based on a round trip time of a UWB signal communicated between the pair of UWB anchor devices. The indoor positioning system also determines a location of each of the UWB anchor devices within the indoor positioning system using the distance measurements, and reconstructs an absolute network topology of the UWB anchor devices using the determined locations of the UWB anchor devices. The absolute network topology is used to determine a location of a client device within the indoor positioning system.
