Which operating concept involves using multiple data links to increase the operational range of an air vehicle?

The concept of using multiple data links to expand the operational range of an air vehicle is best encapsulated by Beyond Line of Sight (BLOS) operations. In BLOS scenarios, a UAS can be operated at distances that exceed the operator’s immediate visual control. This is achieved through the use of various communication links, such as satellite and radio frequencies, allowing for continuous data transmission and control even when the vehicle is far from the operator's direct line of sight.

Beyond Line of Sight operations often require reliable data links to maintain communication, command, and control of the UAS, as the operator cannot rely on visual observation alone. The use of multiple data links further ensures redundancy and enhances the communication capabilities, allowing the vehicle to remain operational over extensive distances while managing various environmental factors and potential obstacles.

This operational concept significantly enhances the versatility and effectiveness of unmanned aerial systems, particularly in applications like search and rescue, surveillance, and logistics, where reaching distant or hard-to-access areas is required.
