Payloads and sensors

Cameras, LiDAR, thermal, multispectral, and other payloads examined as parts of complete evidence systems.

Will this payload integrate with the aircraft and produce evidence fit for the decision?

About this coverage

Payloads and sensors, in practice

A sensor becomes useful only when the aircraft can carry, power, control, time, locate, and record it under the conditions of the mission. Selection therefore begins with the required observation or measurement.

Coverage connects sensor characteristics with physical and electrical integration, calibration, metadata, environmental limits, processing, and acceptance criteria for the final deliverable.
