Beacon mode service
rdfs:comment
The beacon mode service is a Consultative Committee for Space Data Systems (CCSDS) telecommunications service aimed at spacecraft which are not communicated with (on a daily basis) via NASA's Deep Space Network. It is primarily designed to relay a spacecraft's "health" information, and secondarily its telecommunications status, using a simple signal that can be detected with a moderately-sized antenna. Beacon mode also enables spacecraft to communicate with one another on a daily basis, allowing for one spacecraft to act as a data proxy for another.

dbo:abstract
The beacon mode service is a Consultative Committee for Space Data Systems (CCSDS) telecommunications service aimed at spacecraft which are not communicated with (on a daily basis) via NASA's Deep Space Network. It is primarily designed to relay a spacecraft's "health" information, and secondarily its telecommunications status, using a simple signal that can be detected with a moderately-sized antenna. Beacon mode also enables spacecraft to communicate with one another on a daily basis, allowing for one spacecraft to act as a data proxy for another. The CCSDS tone beacon mode configures the transceiver to transmit a CW tone. It can be used to signal other spacecraft to transmit their data to an orbiter; however, its primary function is to transmit spacecraft health information.Addressing multiple spacecraft is accomplished by using four unique CW frequencies with 16 possible tones, used somewhat like DTMF signaling technology. In the outer solar system, UHF frequencies are not used; instead, the primary (or backup) transmitter is programmed to transmit the required tone (generally in the X or Ku band). Spacecraft may respond in any transmit configuration compatible with valid orbiter receive configurations, but outside the beacon mode service.
