There is little doubt that night flying is one of the most challenging environments. Autonomous systems offer a lot of potential for these types of operations. Sonar and LiDAR are great tools that can enhance this capability but a highly experienced pilot in control is our greatest asset.
The video above demonstrates the skill of the pilot as the aircraft is flown via Infra-red FPV along an over grown rural driveway, under trees and undergrowth, in the pitch black of a moonless night.
The video below demonstrates the ability to identify the differences between rabbits, birds and other species using infrared during night operations.
