Which frequency bands are commonly used in remotely piloted aircraft systems?

The selection of S-Band, L-Band, C-Band, and Ku-Band is notable because these frequency bands are widely recognized for their use in remotely piloted aircraft systems (RPAS) and unmanned aerial systems (UAS).

S-Band (2-4 GHz) is often utilized for telemetry, command, and control communications due to its ability to penetrate atmospheric conditions and carry signals over longer distances without excessive bandwidth erosion.

L-Band (1-2 GHz) is frequently employed in aviation for radar systems and communications, providing a balance between range and resolution which is beneficial in navigating and maintaining situational awareness.

C-Band (4-8 GHz) is leveraged for satellite communications and weather radar, making it well-suited for applications where robust signal integrity and range are crucial.

Ku-Band (12-18 GHz) is utilized for satellite communications, including data transmission from aircraft to ground stations, due to its high bandwidth capabilities and efficiency in delivering rich data streams.

These frequency bands are favored in the industry for their reliable performance and regulatory acceptance, which facilitate safe and effective operation of remotely piloted systems in various operational environments. The other frequency bands listed do not typically align with common practices or regulations governing UAS
