Latest Patents

Chuba's latest patents include a method for refining state estimates of a GPS receiver based on sequential GPS carrier phase measurements. This invention utilizes sequential GPS Doppler carrier phase count measurements to achieve precision in determining the position and velocity of a GPS receiver. The method addresses several challenges associated with prior art orbit determination, such as the 'cycle slip' problem and the unknown initial range problem. Additionally, it significantly reduces carrier signal phase variation caused by the rotation of the receiver antenna relative to the transmitter antenna.

Another patent by Chuba is the GPS carrier phase measurement representation and method of use. Similar to his previous invention, this patent also employs sequential GPS Doppler carrier phase count measurements for accurate position and velocity determination. The optimal sequential filter and fixed-lag smoother enable real-time and near-real-time performance, respectively. This innovation further mitigates issues related to overlapping thermal noise and enhances the overall effectiveness of GPS technology.
