Offline apparatus for determining the position of an artificial satellites tens in the region of the said broad band and method therefor

摘要

PROBLEM TO BE SOLVED: To provide an offline attitude determining device capable of detecting the satellite attitude with high accuracy in broad band.;SOLUTION: The averaging and adding processing of a low frequency attitude interpolation signal 15 produced by interpolating a low frequency attitude detecting signal 1 obtained by inputting an attitude angle determining signal 11 produced by a sequential Karman filter computing unit 3 to a low-pass filter computing unit 4, and a high frequency attitude detecting signal 14 obtained by inputting a high frequency attitude angle sensor detecting signal 13 extracted by a high frequency attitude angle sensor data extractor 5, in an attitude data producing unit 8 to produce a high accuracy attitude detecting signal 16. The decision of the broad band attitude can be realized with high accuracy by combining the low frequency attitude detecting signal 12 and the high frequency attitude detecting signal 14 by using an interpolation processing and operating part 7 and an attitude data producing unit 8.;COPYRIGHT: (C)2002,JPO
