Push-to-talk


Push-to-talk (PTT) is a communication method that allows a user to transmit a message over a two-way communication system by pressing a button to activate the microphone. In space and astronautical engineering context, PTT is commonly used in spacecraft communication systems, where it enables astronauts to communicate with each other or with ground control. PTT systems are designed to be reliable and easy to use, with features such as noise-cancelling technology and automatic gain control to ensure clear communication in noisy or low-volume environments. PTT is also used in satellite communication systems, where it enables users to communicate with each other over long distances without the need for a wired connection.
