Abstract

A method for regenerating a pseudo-noise (PN) ranging signal at a spacecraft is presented. This method allows for an increase of up to 30 dB in received downlink ranging power. The increased power can be used to decrease the measurement uncertainty, reduce the time of the measurement, or increase the power allocated to the downlink telemetry. This system is being implemented in the Spacecraft Transponding Modem that is being developed by JPL for NASA.
