Latest Patents

One of his latest patents is a method for determining the distance between a transmitter and a receiver. This invention relates to a multiple carrier smoothing method for navigation satellite signals, particularly a three carrier smoothing method for Galileo signals. It provides a smoothed code solution that is ionosphere-free to the first order, reducing noise to a sub-decimeter level. The method effectively resolves integer ambiguities and demonstrates minimal sensitivity to receiver biases and second-order ionospheric delays. The performance of this method allows for a reduction in the averaging interval to one-third of its current standard value, with results that are geometry independent.

Another significant patent by Guenther is a method for determining biases of satellite signals. This new method for bias estimation on multiple frequencies utilizes a Kalman filter and consists of four steps. Initially, a least-squares estimation of ranges, ionospheric delays, ambiguities, receiver phase biases, and satellite phase biases is performed. The code biases are integrated into the ranges and ionospheric delays, while a subset of ambiguities is mapped to the phase biases to eliminate linear dependencies among the unknown parameters. The accuracy of the bias estimates is then enhanced through a Kalman filter, followed by a sequential fixing of float ambiguities. Finally, a second Kalman filter is employed to separate the receiver and satellite code biases from the ranges.
