Abstract:
PURPOSE: A time synchronization signal insertion satellite navigation compensation signal transmitting/receiving system is provided to exactly confirm a time slot interval of a received signal in a receiver side by inserting a data synchronization signal into time information while maintaining an RTCM format. CONSTITUTION: A transmitting system includes a satellite navigation receiver(2), an atomic timepiece(6), and a data link part(12). The satellite navigation receiver receives a GPS signal and generates difference compensation message. The atomic timepiece(6) in a reference center generates time information in which 1 pps synchronous signal is inserted. The data link part(12) modulates and transmits the difference compensation message and time information to a user. A receiving system includes a data link part and a satellite navigation receiver. The data link part demodulates and obtains the difference compensation message and time information. The satellite navigation receiver displays and outputs a final navigation information location coordinate.

Abstract:
PURPOSE: A flying controller is provided to embody the flying performance of an auto-giro and a fixed wing aircraft within a high speed area at the same time. CONSTITUTION: A flying controller is composed of an operation input control system, a sensor(10) for measuring flying state variation, a sensor(12) for measuring an ambient state, a gyro-copter rotor(1), an integrated controller(8), an operator(4) and an engine(16). The operation input control system makes an optimum roll operation input by comparing an operating signal about a roll with a roll stability functional value. Both sensors sense the flying state and the ambient state, and then the gyro-copter rotor generates upward force. The integrated controller generates an output signal by integrating the data of both sensors. The operator drives the gyro-copter rotor adds and subtracts the output of the integrated controller and the operation input control system. Finally, the engine controls the output of the airplane by adding and subtracting the returning signal of the engine and the operation input of the operation input control system.

PURPOSE: A method for calculating a navigation solution and a position independent to the global positioning system(GPS) by using a linear frequency modulation to a differential global positioning system is provided to attribute to the national security through the activation of a related industry and the construction of an independent positioning and navigation system. CONSTITUTION: A method for calculating a navigation solution and a position independent to the global positioning system(GPS) by using a linear frequency modulation to a differential global positioning system is characterized in that it calculates the relative position and navigation solution of the receiver by receiving the signal of a reference station to be transmitted by the schedule specified for each of the navigation differential global positioning system(DGPS) reference stations. The signal of the reference station is received by adding the linear frequency modulation signal to the DGPS correction signal using a conventional MSK modulation method.
