Title: Inventor Spotlight: Andrew Jonathan Gilbert Rosselet
Introduction
Andrew Jonathan Gilbert Rosselet is a prominent inventor based in Scarborough, Canada, known for his significant contributions to the field of technology. With a total of two patents to his name, his work focuses primarily on enhancing navigation technologies through innovative methods.
Latest Patents
One of Rosselet's latest inventions is a frequency aiding method and system for navigation satellite receivers with crystal oscillator frequency hysteresis. This invention provides a method and apparatus designed to estimate oscillator signal variation due to temperature fluctuations. By closely thermally coupling a temperature sensor with the crystal oscillator in a GPS receiver, the system assists the receiver in acquiring signals more efficiently. During the GPS tracking mode, the invention maintains outer bounds of the temperature-compensated crystal oscillator (TCXO) frequency, accounting for temperature variations. Furthermore, during acquisition mode, it offers an estimated frequency value based on the average of these determined bounds. This method significantly reduces the average time to first fix by addressing hysteresis effects of temperature-induced oscillator signal drift.
