How is navigation doppler lidar user friendly
WebThe NDL offers a viable option to aircraft navigation in areas where the GPS signal can be blocked or jammed by intentional or unintentional interference. The NDL transmits three laser beams at different pointing angles toward the ground to measure range and velocity along each beam using a frequency modulated continuous wave (FMCW) technique. WebDoppler navigation works independently, giving flight crews accurate, jam-resistant guidance and velocity data without interruption. That’s why Doppler navigation is …
