Abstract
A precise ranging and timing system using pseudo-noise bandwidth synthesis to provide precise orbit determination for geosynchronous and low earth orbit satellites, navigation of low earth orbiting satellite through signals transmitted through geosynchronous satellites and precise time-transfer. The system includes a novel signal structure which is comprised of disjoint, narrow band, spectral components spread over a wide bandwidth. The number of spectral components, their individual bandwidths, and their specific spectral locations over the end-to-end spread bandwidth determine the ultimate capabilities and performance achievable. The broad beam transmission of the precise ranging and timing system signal via a geosynchronous satellite provide the precise ranging and timing system capability to suitably equipped users for a multiplicity of purposes including: (1) precise orbit determination, (2) navigation of low-earth orbiting satellites through signals transmitted through geosynchronous satellites, and (3) precise time transfer.
