Radio Propagation Time Of Flight Measurements:

Time Of Flight measurements over multiple paths can be a valuable tool when validating and refining radio propagation models. This presentation will discuss current methods in use and several new projects and designs that are being developed for the HamSCI PSWS program. These will include the “Time-Sync Injector” and associated software, which is used with an Software Defined Radio such as the RX-888 to allow accurate Time Of Arrival measurement of received signals. Also described will be the “Time-Stamp Transmitter”, which generates flexible-format time-stamped signals, and a new receiver design, based on the RX-888, but intended to serve as a platform for future time and frequency measurement projects.
