| description | Disclosed is a satellite navigation signal receiving device for a wide area surveillance system comprising: a GPS receiving unit; and a controlling unit. The GPS receiving unit receives satellite navigation signals. The controlling unit calculates a time error by reading the satellite navigation signals received from the GPS receiving unit and pulse signals of an inner oscillator; controls the inner oscillator and accumulates an amount of accumulated control to allow the inner oscillator to follow the satellite navigation signals depending on the time error when time information is determined as a normal state after detecting forgery of the time information based on an amount of past accumulated control of the inner oscillator; and restores the time information by controlling the inner oscillator to allow the amount of accumulated control of the inner oscillator to converge to a setting value when the forgery of the time information is detected. The present invention can stably operate power.
본 발명은 광역 감시 시스템용 위성항법신호 수신장치가 개시된다. 본 발명의 광역 감시 시스템용 위성항법신호 수신 장치는, 위성항법신호를 수신하는 GPS 수신부; 및 GPS 수신부로부터 수신한 위성항법신호와 내부 발진기의 펄스 신호를 읽어 시각오차를 구하고, 과거 누적된 내부 발진기의 누적 제어량에 기초하여 시각정보의 위변조를 탐지한 후 시각정보가 정상상태로 판정된 경우, 시각오차에 따라 내부 발진기가 위성항법신호를 추종하도록 내부 발진기를 제어하고 누적 제어량에 누적하고, 시각정보가 위변조 탐지로 판정된 경우, 누적된 내부 발진기의 누적 제어량이 설정값에 수렴하도록 내부 발진기를 제어하여 시각정보를 회복시키는 제어부;를 포함하는 것을 특징으로 한다. |
