What is a primary service provided by SATCOM systems?

SATCOM systems, or Satellite Communication systems, are designed to facilitate long-distance communication by transmitting signals to and from satellites. One of the primary services provided by these systems is two-way voice communication. This service is crucial for critical operations, where real-time voice communication is necessary, such as in military applications, emergency response, maritime operations, and remote area communications.

The ability to establish two-way voice communication over satellite links enables users to communicate effectively regardless of their location, making it a vital service in areas where terrestrial communication infrastructure is lacking or unreliable. These systems can provide not only voice communication but also the necessary bandwidth and reliability for ensuring efficient conversation even under adverse weather conditions.

The other choices reflect some capabilities that may be supported by satellite systems, such as data transfer and video streaming; however, two-way voice communication is considered a core function, as it directly supports real-time interaction which is essential in many operational contexts.
