摘要： A GNSS(Global Navigation Satellite System) navigation receiver and an operation method thereof are provided to shorten a TTFF(Time to First Fix) by generating valid ephemeris information by an estimation of a present time and a position. A GNSS navigation receiver includes a RF receiving part(210), a demodulating part(220), a navigation data generating part(230), a time/position estimating part(240), an ephemeris information generating part(250), a memory part(260), and a control part(270). The RF receiving part receives a GNSS navigation satellite signal from a GNSS satellite, and outputs a digital data after converting the GNSS navigation satellite signal. The demodulating part demodulates the outputted digital data, and searches a frequency uncertainty and a code delay, and demodulates an original signal from the digital data through a demodulating process. The navigation data generating part generates a navigation data by using the demodulated digital data, extracts information related to navigation information from the demodulated digital data, and generates a navigation data based on the extracted information.

摘要： A satellite control system using a communication satellite and its method are provided to effectively cope with a natural disaster or a failure of a communication network by generating an interface between a central monitoring control station and a satellite control system through a communication satellite without using a terrestrial network infrastructure. A communication satellite link unit receives a command for remote monitoring from a central monitoring control station through a communication satellite(402). An interface unit analyzes the command and determines destination of the command(404). The interface unit converts the command into a remote command to be transmitted to a satellite or a monitoring control command for monitoring and controlling a satellite control system(406). A control satellite link unit receives the converted remote command and transmits it to a satellite, or system monitoring controllers monitor and control a corresponding equipment according to the monitoring control command(408). A communication satellite link unit receives telemetry data received by the control satellite link unit from the satellite and transmits it to the central monitoring control station, or the communication satellite link unit receives a corresponding processing result related to the monitoring control command and transmits it to the central monitoring control station(410).
