In general, both civil and military communications can use carrier technology combined with frequency division multiplexing and time division multiplexing (FDMA/TDMA), and a communication protocol based on demand division 5 (DAM A) to upload incoming signals as communication satellites. . However, the carrier frequency of the civilian communication is usually fixed, and the carrier of the military communication will quickly change the carrier frequency or the jitter frequency within a large bandwidth.

If the common civil communication and military confidential communication systems use different frequencies, the multiplexer 1902172 mode converter (0MT) must be replaced by a frequency multiplexer (MUX), as shown in Figure (3) and Figure 3B. Broadcast signals transmitted by direct broadcast services (such as high-definition TV) and multicast services can be forwarded to analog switches (or digital video broadcast standard channels) after being down-converted to intermediate frequency signals. It is not necessary to go through the process of demodulation and remodulation. This network setup can significantly reduce the load on the internal digital processor of the satellite.
