Title: Innovations of William R Mercer
Introduction
William R Mercer is a notable inventor based in Belmont, MA (US). He has made significant contributions to the field of navigation technology, holding a total of 3 patents. His work primarily focuses on Loran-C signal processing and navigation systems.
Latest Patents
One of his latest patents is the Loran-C signal processor. This invention processes radio frequency Loran-C signal pulses on a point-by-point, cycle-by-cycle basis. It provides the ability to locate a tracking point on each pulse, which is essential for accurate time difference of arrival measurements between successively received signal pulses. This innovation also improves the signal-to-noise ratio of the received signal.
Another significant patent is the Loran-C navigation apparatus. This device utilizes digital circuitry and a microprocessor to automatically identify Loran transmitting stations. It makes standard hyperbolic navigation measurements, allowing the operator to manually enter a group repetition rate. The receiver analyzes all received signals until it regularly receives signals from a master and secondary station at the stored group repetition rate. The apparatus then shifts to a fine search mode to determine the exact time of receipt of the signals, check the phase code, and make time difference of arrival measurements. The output can be plotted on a Loran-C chart to locate the position of the craft.
