ground station generating the time-frequency reference information),
wherein the frequency reference generator generates a frequency reference signal in a first frequency band (See p.3; [4]; wherein the time-frequency reference information comprises a reference frequency signal of the navigation modulation signal. A frequency signal is somewhat in a frequency band); and
a communication receiving channel of the ground communication system (See p.4; [2-5]; p.7; [9-10]; receiver of the ground station received transmitted modulated signal with spread spectrum code),
wherein the channel is configured (See p.3; [4]; the ground station generated the reference frequency to be used for modulation and demodulation) for receiving a direct spread or frequency hopped signal from a satellite or an aircraft (See p.4; [2-5]; p.7; [9-10]; ground station receiving generating timecode data and spread spectrum code data based on the time frequency reference information) using the frequency reference signal in the first frequency band (See p.3; [6]; generating timecode data and spread spectrum code data based on the time frequency reference information in a frequency band; A spread spectrum code modulation signal based on the reference frequency signal is generated by the time code data and the spread spectrum code data),
wherein a legacy satellite system comprises a legacy ground communication transmitting channel for transmitting data from earth (See p.3; [1]; p.8; [2]; the pseudo-range obtained by the satellite receiver is emitted from the ground station) to a legacy satellite using the first frequency band (See p.3; [1]; p.8; [2]; a frequency is used among the infinite frequency in the L/C/Ku band to emit signal to the legacy satellite) and a legacy ground communication receiving channel for receiving data on earth from the legacy satellite using a second frequency band (See p.2; [3]; p.8; [3]; in the satellite navigation system, basically adopts direct broadcasting type navigation mode, the ground receiver receives modulated signal from the satellite using one frequency in the L/C/Ku band))).
