The early navigation system was inertial-based; point-of-origin coordinates were programmed into a navigation computer and gyroscopes would track the aircraft's every motion to calculate distance and direction from that starting point.
Sistem navigasi inersia awal adalah berbasis point-of-asal koordinat yang diprogram ke dalam komputer navigasi dan giroskop akan melacak pesawat setiap gerak untuk menghitung jarak dan arah dari titik awal.
