In this paper, Design, optimization and implementation of a Transparent Pseudo-Noise satellite Ranging relay is presented. CCSDS and DSN standards was studied for requirements of on board harware for LEO satellites and ground station. To optimize the performance of the relay, a ground station for two-way ranging system was modeled in MATLAB according to the DSN standard architecture. The effects of non-ideal hardware for Implementation of on-board relay was simulated. The simulation results confirmed that the designed transparent relay hardware satisfies the requirements of CCSDS and DSN ranging standards system and has no detrimental effect on it. Finally, the implemented relay was tested with a Transceiver similar to the ranging Transceiver was confirmed for operation.
