Multi-Hop Positioning - A simplified explanation of the abstract
This abstract first appeared for US patent application 18489299 titled 'Multi-Hop Positioning
Simplified Explanation
The patent application describes a process for estimating the position of a device based on distance and angle estimates obtained from another device. The first device obtains information from a second device, including direct distance estimates and direct angle estimates between the second device and a third device. The first device then determines a position estimate based on the obtained distance and angle estimates. The first device and the third device may be out of range for direct distance measurement.
- The process involves obtaining distance and angle estimates from a second device.
- The position of the first device is estimated based on the obtained estimates.
- The first device and the third device may be out of range for direct distance measurement.
Potential Applications:
- Indoor positioning systems: The technology can be used to estimate the position of devices in indoor environments where direct distance measurement is not possible.
- Asset tracking: The process can be applied to track the location of assets within a facility or a large area.
- Navigation systems: The technology can enhance navigation systems by providing accurate position estimates even in situations where direct distance measurement is not feasible.
Problems Solved:
- Limited range for direct distance measurement: The technology solves the problem of estimating positions when the first and third devices are out of range for direct distance measurement.
- Indoor positioning challenges: The process addresses the difficulties in accurately estimating positions in indoor environments where GPS signals may be weak or unavailable.
Benefits:
- Improved accuracy: By combining distance and angle estimates, the technology provides more accurate position estimates compared to traditional methods.
- Cost-effective: The process eliminates the need for expensive infrastructure or equipment for direct distance measurement.
- Versatile: The technology can be applied in various scenarios, including indoor environments and situations where direct distance measurement is not possible.
Original Abstract Submitted
In one aspect, a process for position estimation entails, at a first device, obtaining from a second device information including (a) at least one direct distance estimate corresponding to a distance between the second device and a third device, (b) at least one direct angle estimate corresponding to a spanning angle formed involving the second device and a third device, or both (a) and (b). The process may further entail, at the first device, determining a position estimate for the first device based on (a) the at least one direct distance estimate, (b) the at least one direct angle estimate, or both (a) and (b). The first device and the third device may be out of range with respect to one another to make a direct distance measurement between the first device and the third device.
