Quasi-ADS-B Based UAV Conflict Detection and Resolution to Manned Aircraft

Algorithm 3

PGD CD&R architecture.

Initialization   System initialized and GPS lock

REPEAT every second

   INPUT Intruders GPS data

    Predict future trajectory and position (next 25 seconds = 25 grids)

    Overlap of each aircraft same time stamp grids

    IF A grid block value > threshold value

      Mark block as dangerous zone

      Issue PA

      TSR CD&R execute

    ENDIF

UNTIL Shutdown
