Juno (spacecraft) - Telecommunications

Telecommunications

Juno's telecommunication systems have more in common with New Horizons than with Cassini–Huygens spacecraft. Juno supports tone fault signalling for cruise mode operations, but it is expected to be used less often. Communications are via the 70 m antennae of the Deep Space Network (DSN) utilizing an X-band direct link. The Command & Data processing of the Juno spacecraft includes a flight computer capable of providing ~50 Mbit/s of instrument throughput. Gravity science subsystems use X-band and Ka-band doppler tracking and autoranging.
