Latest Patents

Usman's latest patents focus on innovative systems and methods for ionospheric correction. The first patent, titled "Ionospheric correction for single frequency GPS receivers using three satellites," describes a method where a single GPS frequency receiver determines the geographic location of an object on the earth's surface. This system utilizes signals from three GPS satellites, ensuring that the total electron count (TEC) contribution to ionospheric interference is approximately the same for all satellites. By measuring the distances of the satellites based on actual signal transmission times, the true distances can be calculated, leading to improved accuracy in location determination.

The second patent, "Ionospheric correction for single frequency GPS receivers using two," employs a similar approach but utilizes signals from two GPS satellites. This method also aims to achieve an equal TEC contribution to ionospheric interference, allowing for accurate distance measurements and location determination.
