METHOD FOR CALCULATING NAVIGATION SOLUTION AND POSITION INDEPENDENT TO GLOBAL POSITIONING SYSTEM BY USING LINEAR FREQUENCY MODULATION TO DIFFERENTIAL GLOBAL POSITIONING SYSTEM

摘要

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.
