AEHF, or Advanced Extremely High Frequency, is a satellite communication system designed to provide secure and reliable communications for the United States military and its allies. It operates in the extremely high frequency band, allowing for enhanced data transmission capabilities, even in contested environments. The AEHF system consists of multiple satellites in geostationary orbit, ensuring global coverage. It supports various communication needs, including voice, video, and data, while maintaining resistance to jamming and interception. This makes AEHF crucial for military operations, ensuring that forces can communicate effectively in any situation.
