Title: Michael T Grabbe: Innovator in Geo-Location Technology

Introduction

Michael T Grabbe is a notable inventor based in Wylie, TX (US). He has made significant contributions to the field of geo-location technology, holding a total of 3 patents. His work focuses on developing advanced algorithms and methods for accurately estimating the location of non-cooperative targets.

Latest Patents

One of Grabbe's latest patents is the "Globally-convergent geo-location algorithm." This innovative system and method estimate the geolocation of a non-cooperative target using various signal measurements. Collectors can acquire actual signal measurements, including direction of arrival (DOA), target range, time difference of arrival (TDOA), range rate, range sum, and frequency difference of arrival (FDOA). A processing device receives these measurements and navigational data, calculating an estimated target location through a nonlinear optimization problem. The algorithm employed to solve this problem is a globally convergent algorithm, such as the Levenberg-Marquardt algorithm.

Another significant patent is the "Method and apparatus for signal tracking utilizing universal algorithm." This invention provides a method and apparatus for signal tracking that includes acquiring a signal measurement, forming a measurement matrix, and applying this matrix to a recursive filter to determine the geolocation of the signal. This configuration allows for geolocations to be determined using any signal measurement or combination of measurements, eliminating the need for a specific static combination.
