What type of remote sensing payload should be used for tracking lost wildlife or individuals with cognitive conditions?

The choice of a remote sensing payload for tracking lost wildlife or individuals with cognitive conditions revolves around the capabilities and functionalities of different sensor types. Active sensors emit their own signals and measure the reflections from objects to gather data, which makes them suitable for certain applications. However, in sensitive tracking scenarios, such as monitoring wildlife or individuals, the advantages of passive sensors come into play.

Passive sensors detect naturally occurring radiation, like infrared or visible light, and often rely on existing signals in the environment. Because they do not emit signals, passive sensors tend to be less intrusive and can operate in stealthier ways which is essential for wildlife tracking. This means they can gather data without alerting or disturbing the subjects being monitored, making them ideal for tracking lost wildlife or individuals with cognitive conditions.

Using passive sensors minimizes the risk of interfering with the behavior of the individuals or animals being tracked, allowing for more accurate and humane monitoring. This capability is critical in scenarios where the safety and well-being of the subject are paramount.
