Title: Innovations by Jonathan Ladd
Introduction
Jonathan Ladd is an accomplished inventor based in Bridgewater, NH (US). He has made significant contributions to the field of GNSS technology, holding three patents that showcase his innovative approach to improving positioning systems. His work focuses on utilizing existing signals of opportunity to enhance the performance and accuracy of GNSS receivers.
Latest Patents
One of Jonathan Ladd's latest patents is a GNSS receiver that uses signals of opportunity and assistance information to reduce the time to first fix. This innovative receiver leverages properties of existing radiated signals, such as AM or FM radio signals and television signals, to minimize uncertainties associated with oscillator frequency and phase. By utilizing an Almanac and a battery-backed date and time, the receiver can determine the satellites in view, further reducing uncertainties related to Doppler effects.
Another notable patent is a system for determining position over a network. This system utilizes signals of opportunity transmitted by one or more transmitters with known locations. It includes a base receiver that determines ranges to the transmitters and time tags a series of samples of the signals of opportunity. The remote receivers then calculate their position based on time offsets and ranges provided by the base receiver, allowing for accurate positioning even in challenging environments.
