摘要： Provided are a method and apparatus for compensating an attitude of an inertial navigation system and a method and apparatus for calculating a position of the inertial navigation system using the same. The method of compensating an attitude of the inertial navigation system includes sensing movement of the system and outputting information for stoppage time periods and a movement time period of the system; receiving angular velocity information of the system during every time period and calculating a first attitude of the system using the angular velocity information; receiving gravity direction information of the system during the stoppage time periods, calculating a second attitude of the system using the gravity direction information, and calculating an attitude error of the system during every time period using the first attitude and the second attitude; and compensating the attitude error for the first attitude.

摘要： In a data communication system having a network composed of a central facility, a plurality of relay units, and a plurality of terminal units, traffic information, which may contain information about a number of calls and a total amount of communication time occurred with respect to each relay unit over the predetermined interval, is sent from the relay units to a communication control unit. A ROM stores a threshold value for each relay unit and comparison is made to compare the received traffic information with the corresponding threshold value. Then, the is determined whether the subject relay unit is in a high-load condition. If so, relay units and terminal units that are scheduled to call the high-load relay unit are detected so that those units bypass the high-load relay unit.
