A known ground location (KGL) satellite transceiver can include a position and elevation acquisition module configured to determine a time of flight (TOF) of a pseudonoise (PN) signal and a Doppler shift in a KGL signal for use in determining an orbit of a satellite. The PN signal can include a transmitted PN signal and a transponded PN signal. The KGL signal can include a transmitted KGL signal and a transponded KGL signal. The transmitted PN signal and the transmitted KGL signal can be transmitted sequentially on a first frequency carrier from the KGL satellite transceiver to the satellite. The transponded PN signal and the transponded KGL signal can be retransmitted back sequentially on a second frequency carrier from the satellite to the KGL satellite transceiver. The first frequency carrier and the second frequency carrier use a same frequency carrier or a different frequency carrier from each other.
