Abstract: A global navigation satellite system (GNSS) signal output system is proposed. The system may include a signal generating apparatus configured to receive GNSS navigation information and generate, based on the GNSS navigation information, a pseudo GNSS signal corresponding to a current time and a current location. The system may also include a plurality of leakage cables including a plurality of signal leakage slots. The system may further include a plurality of signal output apparatuses configured to receive the pseudo GNSS signal from the signal generating apparatus and output the pseudo GNSS signal to at least one of the plurality of leakage cables. The plurality of signal output apparatuses may be arranged apart from each other.

Abstract: This application relates to an apparatus for generating a global navigation satellite system (GNSS) signal. In one aspect, the apparatus includes a receiver configured to receive and store GNSS navigation information, receive a real-time satellite signal, and calculate a frequency shift value of the real-time satellite signal with respect to a default carrier frequency based on the real-time satellite signal. The apparatus may also include at least one signal generator configured to receive the GNSS navigation information from the receiver, and generate pseudo GNSS signal information corresponding to a current time and a current location based on the GNSS navigation information and the frequency shift value. The apparatus may further include a transmitter configured to generate a pseudo GNSS signal based on the pseudo GNSS signal information, and amplify and output the pseudo GNSS signal, wherein the GNSS navigation information indicates an estimated location of a GNSS satellite over time.
