The BSU receives commands from the SDU and converts
them in order to control an electronic antenna to point
its beam at the satellite.
BITE
The SDU is interfaced with the CFDIU for BITE purposes
via an ARINC 429 bus.
The HPA and BSU can be tested through the SDU via ARINC
429 buses. They also provide HGA and D/LNA status.
