Samsung patents AI method to improve GPS accuracy in devices

Samsung has filed a patent for a method that uses machine learning to adjust how a GPS receiver processes satellite signals. The system trains a model to minimize errors in distance measurements from satellites, which helps the device calculate its position or speed more accurately.

Why it mattersThis could lead to more precise location data for navigation apps and other features that rely on GPS in smartphones and other devices.

In the filing’s own words

A system and a method are disclosed for determining global navigation satellite system (GNSS) measurement weighting. Determining the GNSS measurement weighting includes determining, using a processor in a GNSS receiver, at least one of a pseudorange or a pseudorange rate and minimizing, by training a machine learning (ML) model, a prediction error of the at least one of the pseudorange or the pseudorange rate. Determining the GNSS measurement weighting also includes determining, with the ML model, solver weights for a GNSS solver based on the minimization of the prediction error and providing, with the processor, the solver weights to the GNSS solver to predict at least one of a position or a velocity of the GNSS receiver. The prediction error is based on a difference between a predicted measurement error and a true measurement error of the pseudorange and the pseudorange rate.

What exactly they claim (claim 1)

1. A method comprising: determining, with a processor in a global navigation satellite system (GNSS) receiver, at least one of a pseudorange or a pseudorange rate of the GNSS receiver relative to a GNSS satellite; minimizing, by training a machine learning (ML) model, a prediction error of the at least one of the pseudorange or the pseudorange rate; determining, with the ML model, solver weights for a GNSS solver in the GNSS receiver based on the minimization of the prediction error; and providing, with the processor, the solver weights to the GNSS solver to predict at least one of a position or a velocity of the GNSS receiver; wherein the prediction error is based on a difference between a predicted measurement error and a true measurement error of the pseudorange or the pseudorange rate.
