1. A communication method for transmitting meta-data through a meta-carrier signal, the method comprising: encoding meta-data configured for use by an earth station to identify at least one repeating relay using an encoder, the meta-data comprising information that identifies or describes a repeating relay or one or more transponders of the repeating relay to which a spread meta-carrier signal is to be transmitted, the information comprising at least one of a name of a repeating relay, a name of a transponder, a transponder center frequency, a transponder polarization, and an ephemeris; modulating, using a modulator, the encoded meta-data signal; spreading, using a spreader, the modulated meta-carrier such that the spread meta-carrier signal results; andtransmitting, by a transmitting device, the spread meta-carrier signal to the repeating relay wherein the spread meta-carrier signal is transmitted over at least a portion of the bandwidth of the repeating relay without reserving the at least a portion of the bandwidth solely for transmitting the spread meta-carrier signal and at a signal power level that is embedded into the noise floor of the repeating relay. 2. The method of claim 1, further comprising: receiving the spread meta-carrier signal by a receiving device;despreading, using a despreader, the spread meta-carrier signal;demodulating, using a demodulator, the de-spread meta-carrier signal; anddecoding, using a decoder, the demodulated meta-carrier signal. 3. The method of claim 1, wherein the spread meta-carrier signal is transmitted over substantially the entire bandwidth of the repeating relay. 4. The method of claim 1, wherein the repeating relay is located on a satellite. 5. The method of claim 1, wherein the modulating uses a phase shift keying (PSK) technique. 6. The method of claim 1, wherein the spreading uses a predetermined pseudo-random-noise (PRN) sequence. 7. The method of claim 1, further comprising: extracting, by a beacon extraction device within the repeating relay, the spread meta-carrier signal;routing, by the beacon extraction device, the spread meta-carrier signal to a beacon injection device; andembedding, by the beacon injection device, the spread meta-carrier signal to one or more transponders. 8. The method of claim 7 further comprising: routing, by the beacon extraction device, the meta-carrier signal to a beacon processor; andprocessing, by the beacon processor, the meta-carrier signal to form a processed meta-carrier signal. 9. The method of claim 8, wherein the processing creates a unique meta-carrier signal for each transponder. 10. The method of claim 8, wherein the processing creates a substantially identical meta-carrier signal for each transponder. 11. The method of claim 8, further comprising: retaining, by the beacon processor, the processed meta-carrier signal; andloading, by the beacon processor, the processed meta-carrier signal when the repeating relay is created. 12. A communication system for transmitting meta-data through a meta-carrier signal, the system comprising: an encoder configured to encode meta-data that is configured for use by an earth station to identify at least one repeating relay, the meta-data comprising information that identifies or describes a repeating relay or one or more transponders of the repeating relay to which a spread meta-carrier signal is to be transmitted, the information comprising at least one of a name of a repeating relay, a name of a transponder, a transponder center frequency, a transponder polarization, and an ephemeris; a modulator configured to modulate the encoded meta-data signal; a spreader configured to spread, the modulated meta-carrier such that the spread meta-carrier signal results; anda transmitting device configured to transmit the spread meta-carrier signal to the repeating relay wherein the spread meta-carrier signal is transmitted over at least a portion of the bandwidth of the repeating relay without reserving the at least a portion of the bandwidth solely for transmitting the spread meta-carrier signal and at a signal power level that is embedded into the noise floor of the repeating relay. 13. The system of claim 12, further comprising: a receiving device configured to receive the spread meta-carrier signal;a despreader configured to despread the spread meta-carrier signal;a demodulator configured to demodulate the de-spread meta-carrier signal; anda decoder configured to decode the demodulated meta-carrier signal. 14.

The system of claim 12, wherein the repeating relay is located on a satellite. 16. The system of claim 12, wherein the modulator is further configured to use a phase shift keying (PSK) technique. 17. The system of claim 12, wherein the spreader is configured to spread using a predetermined pseudo-random-noise (PRN) sequence. 18. The system of claim 12, further comprising: a beacon extraction device within the repeating relay that is configured to extract the spread meta-carrier signal; anda beacon injection device configured to embed the spread meta-carrier signal to one or more transponders after receiving the spread meta-carrier signal as routed by the beacon extraction device. 19. The system of claim 18 further comprising: a beacon processor configured to receive the meta carrier signal as routed by the beacon extraction device and process the meta-carrier signal to form a processed meta-carrier signal. 20. The system of claim 19, wherein the beacon processor is further configured to create a unique meta-carrier signal for each transponder. 21.
