With a total of 2 patents, Kelley has focused on enhancing the accuracy and efficiency of satellite navigation systems.
Latest Patents
Kelley's latest patents include a "Method and apparatus for modeling of GNSS pseudorange measurements for interpolation, extrapolation, reduction of measurement errors, and data compression." This invention utilizes polynomial regression models to minimize errors in pseudorange measurements between GNSS satellites and receiving stations. It also allows for data compression by replacing numerous measurements with a few coefficients of the model polynomial. Additionally, it provides accurate estimates of future range and coefficient values of the polynomial regression models.
Another significant patent is the "Method and apparatus for reducing satellite position message payload by adaptive data compression techniques." This adaptive method compresses Differential GNSS corrections by decomposing each measurement datum into an anchor value and a delta value. In some cases, a nonce value is also included. The encoding parameters are adjusted adaptively based on changing data and transmission medium characteristics, allowing for effective handling of anomalous conditions.
