Which remote sensing payload can be used for tracking tagged wildlife, lost or wandering adults, or children suffering from cognitive conditions?

• A. Active radar
• B. LIDAR
• C. GPS collar
• D. Passive radio wave tracking device

Answer: (D)

Tracking moving subjects over distance relies on a system that can determine location and relay it to a monitoring station. A GPS collar does this by carrying a GPS receiver and a transmitter, giving precise coordinates of the wearer or animal in real time or near real time. This approach is used for wildlife studies and for people who wander or have cognitive conditions because it provides ongoing location data across large areas without requiring proximity to a specific recorder. Active radar and LIDAR are powerful sensing methods but are not designed for continuous location tracking of tagged individuals across wide areas in everyday settings; radar detects objects and measures range, while LIDAR maps surroundings using light. Passive radio wave tracking devices rely on being read by nearby receivers; they don’t continuously broadcast position over large distances, making them impractical for constant tracking of subjects over wide areas. Therefore, a GPS collar is the best option for tracking tagged wildlife, lost adults, or children with cognitive conditions.
