What type of links do satellites primarily utilize in military communications?

Satellites in military communications predominantly utilize UHF (Ultra High Frequency) and SHF (Super High Frequency) line of sight links due to their ability to effectively send and receive signals over long distances with minimal interference.

UHF frequencies are commonly used for various forms of communication, including voice and data transmissions, and are valuable for their ability to penetrate through obstacles like foliage and buildings, making them ideal for tactical military operations. SHF frequencies, on the other hand, are typically used for satellite communications and radar applications. They offer higher bandwidth, which supports a greater data throughput, critical for modern military operations that rely on rapid communication and real-time data sharing.

Understanding these frequency ranges is essential in military operations, as they determine the effectiveness of communication systems in diverse terrains and environments. The use of line of sight for these frequencies is important because satellite communications require a clear path between the transmitter and receiver, which is achieved through satellite alignment and positioning.
