Abstract
A method and a system for reducing time to first fix (TTFF) in a satellite navigation receiver (SNR) includes constructing an integrated satellite constellation system (ISCS) for transmitting navigation signals over a combination of a first carrier frequency, a second carrier frequency, and a third carrier frequency. The ISCS includes a predetermined number of geosynchronous satellites positioned at first predetermined geographic coordinates in a geosynchronous orbit and a predetermined number of geostationary satellites positioned at second predetermined geographic coordinates in a geostationary orbit. The ISCS transmits navigation data to the SNR over the combination of the first carrier frequency, the second carrier frequency, and the third carrier frequency in reduced time, thereby reducing the TTFF in the SNR. The method and the system also reduce TTFF in a hot start mode and a snap start mode of the SNR by utilizing the third carrier frequency as a data channel.
