Which of the following data links would enable Beyond-Line-of-Sight operations?

Beyond-Line-of-Sight (BLOS) operations require a data link that can communicate over long distances, beyond the operator's visual range, to maintain control of an Unmanned Aircraft System (UAS). Iridium SATCOM is a satellite communication technology that provides coverage across the entire earth, allowing for communication in remote areas or over oceans where other data links wouldn't function effectively. This capability to maintain a continuous connection over vast distances makes it suitable for BLOS operations.

In contrast, Wi-Fi networks typically operate within a limited range and are designed for short-distance communication, which makes them unsuitable for BLOS. Bluetooth connections have an even shorter range and are primarily focused on personal area networks. Standard radio frequency communication can cover longer distances but is often limited by line-of-sight constraints and terrain, making it less reliable than satellite communications like Iridium. Thus, Iridium SATCOM stands out as the best option for enabling BLOS operations due to its extensive coverage and reliability.
