Abstract: A method for landing aircraft is provided to enhance the integrity of satellite navigation system by checking the integrity of a navigation receiver of the aircraft using aircraft position information and transmitting the checked content to a control office. Navigation signals of plural navigation satellites are received and navigation signals of plural pseudo satellites, which are installed at a landing route of an aircraft, are received(S401,S402). The integrity of the navigation and pseudo satellites is estimated by using the navigation signals and then the estimated result is sent to the aircraft. Aircraft position information from the aircraft is received and aircraft position information from a control office is received(S403). The integrity of a navigation receiver of the aircraft is estimated by using the aircraft position information and then the estimated result is sent to the control office(S405).

Abstract: A method and an apparatus for sensing the posture of a satellite are provided to obtain the posture of the satellite through numerical processing of a visual image. A method of sensing the posture of a satellite includes the steps of photographing an image of the earth using an image photographing part(S201), determining whether solar eclipse is generated(S202), filtering strong solar light to transmit the light to a posture signal generating part(S203), allocating a photograph image region to the posture signal generating part(S204), obtaining an earth boundary region(S205), calculating variation of the earth boundary region(S206), determining whether the variation value is normal(S207), converting the calculated variation value into an posture signal(S208), and initializing image information(S209).
