    • A time correcting apparatus includes a data input section which inputs all event trace data generated for each event executed on computing devices and outputs the event trace data in order of occurrence time of the event data. An inter-machine communication-time-table generating section extracts transmission and reception events from the output event trace data and generates a communication time table indicating communication times between computing devices based on the differences in occurrence time between the corresponding transmission and reception events. A time-offset deriving section generates a time offset table indicating a time offset value for each computing device based on the communication time table. A time correcting section corrects the event occurrence times of all event data based on the time offset table. A data integrating section inputs all event data whose occurrence times have been corrected and outputs the event data in order of corrected occurrence time.

    • A 6-degree-of-freedom control apparatus for a spacecraft includes a plurality of thrusters, thruster modulator, position/velocity detector, target position/velocity generator, attitude/angular velocity detector, target attitude/angular velocity generator, and 6-degree-of-freedom controller. The thrusters control three position axes and three attitude axes of a spacecraft by jet. The thruster modulator selectively drives the thrusters on the basis of a thruster control signal. The position/velocity detector measures a position and velocity of the spacecraft. The target position/velocity generator generates target position and velocity values of the spacecraft. The attitude/angular velocity detector measures an attitude and angular velocity of the spacecraft. The target attitude/angular velocity generator generates target attitude and angular velocity values of the spacecraft. The 6-degree-of-freedom controller generates the thruster control signal on the basis of a deviation between an output from the position/velocity detector and an output from the target position/velocity generator and a deviation between an output from the attitude/angular velocity detector and an output from the target attitude/angular velocity generator and outputs the signal to the thruster modulator.

    • An attitude angle sensor correcting apparatus for an artificial satellite of the present invention includes a satellite attitude estimator. The satellite attitude estimator reads geographical image data out of an image data memory, produces a GCP (Ground Control Point) position included in the image data by stereo image measurement, and then estimates the instantaneous satellite attitude angle on the basis of a relation between the measured GCP position and a true GCP position. An attitude angle sensor data corrector corrects measured attitude angle data with estimated satellite attitude data output from the satellite attitude estimator and corresponding in time to the measured attitude angle data. The attitude angle sensor data corrector outputs an estimated satellite attitude signal.
