CPS of MLAT and aircraft position calculation method using the same

摘要

The present invention discloses a central processing apparatus for a multi-sided measurement detection system and a method for calculating aircraft position using the same. The central processing unit of the present invention groups signals transmitted at the same time among input units receiving signals including time of arrival (TOA) for a plurality of time-synchronized receivers and signals input from the input unit. (grouping), corrects the bias factor for the signal arrival time of the receivers corresponding to the grouped signal to be the same, and receives a time difference of arrival (TDOA) between receivers based on the corrected signal arrival time. ), and a control unit for calculating the position of the aircraft using the calculated reception time difference.
