摘要： Disclosed are an apparatus and method for computing a vehicle path by considering satellite communication channel states. The method includes: searching for a plurality of candidate paths, each path connected from a starting point to a destination; analyzing a satellite communication channel state with respect to each of the candidate paths, based on a receiving sensitivity of an electric wave received from a satellite; setting one of the candidate paths as a first path, based on the analyzed satellite communication channel states; and mapping the first path onto a map, and displaying the first path on a display unit.

摘要： A stabilization control method for a satellite tracking antenna disclosed herein includes outputting a monopulse signal and a gyro signal through a satellite tracking antenna having a gyro mounted thereto, under a situation that disturbance is applied to the satellite tracking antenna, inputting the output monopulse signal and gyro signal into a Kalman filter for stabilization of the satellite tracking antenna, defining a state vector of the Kalman filter based on a pointing-error angle for the satellite tracking, corresponding to the monopulse signal, and a pointing-error angular velocity for the satellite tracking, corresponding to the gyro signal, predicting an original monopulse signal corresponding to a state prior to distortion of the monopulse signal based on the defined state vector, and continuously updating the prediction of the original monopulse signal, and carrying out the stabilization control for the satellite tracking antenna by using the predicted original monopulse signal as a pointing-error-correcting input value.
