Samsung patents method to fix indoor GPS errors caused by people
Samsung has been granted a patent for a method that improves indoor positioning accuracy by accounting for human interference. The system uses ranging devices and sensors to detect when a person blocks the signal, then applies a correction to the distance measurements to calculate a more accurate location.
In the filing’s own words
A method for estimating a position of a moving object comprises receiving one or more ranging measurements for distances between an object and one or more anchor points from a ranging device, receiving sensing data from one or more sensors, determining a distance and a heading direction of the object relative to a position of the one or more anchor points based on the one or more ranging measurements and the sensing data, applying a mapping using the distance and the heading direction of the object to correct the ranging measurements, and determining a position of the object based on the corrected ranging measurements.
What exactly they claim (claim 1)
1. A method for estimating a position of a moving object, the method comprising: receiving one or more ranging measurements for distances between an object and one or more anchor points from a ranging device; receiving sensing data from one or more sensors; determining a distance and a heading direction of the object relative to a position of the one or more anchor points based on the one or more ranging measurements and the sensing data; applying a mapping using the distance and the heading direction of the object to correct the ranging measurements; and determining a position of the object based on the corrected ranging measurements.
