Which of the following is NOT true regarding the COSPAS-SARSAT system?

The assertion that the COSPAS-SARSAT system may be used to transmit public correspondence is not true. COSPAS-SARSAT is a satellite system specifically designed for search and rescue operations, primarily to detect and locate distress signals from emergency beacons, such as EPIRBs (Emergency Position-Indicating Radio Beacons). The system operates on specific frequencies, predominantly the 406 MHz band, to ensure prompt response in emergencies.

The primary function of COSPAS-SARSAT is to facilitate the urgent reporting of distress situations to search and rescue authorities, rather than functioning as a communication tool for general public correspondence. This dedicated purpose distinguishes the system from others that may support various types of data transmission, illustrating the focused mission of COSPAS-SARSAT in providing life-saving assistance during emergencies.
