첫댓글 GPS 재밍이 되어도 아주 정확한 항법이 되면 거의 모든 항공기의 필수품이 될 것 같습니다.
가격은 비쌀 것 같지만 사이즈는 소형화가 가능한 것 같더라구요. 탄도탄 뿐만 아니라 잠수함 등도 정확한 항법이 가능해진다고 하니 실용화된다면 필수 기술이 될 것 같습니다.
정확한 원리는 잘 모르겠습니다만, 양자위성이 아닌 상태에서 수신측만으로도 재밍을 효과적으로 회피가 가능한건가요? 송신측도 양자화된 신호를 보내야중간에 해킹이나 재밍되도 안전한 거 아닌지...
GPS처럼 외부에서 신호를 받는 게 아니라 극저온으로 냉각해 양자 중첩 상태로 만든 원자의 상태를 관측하는 일종의 관성항법장치같습니다.
