BUTCube - Communnication

cube-sat, mission demonstrator, communication board, satellite, 1U concept

Satellite communication board manage basic communication which is beacon, define
GPS coordinates of the satellite and transfer data to tha base station. The board
allow to get data directly from the camera or receiveing data from the control
board using QSPI interface.


The board has main stack connector to connection between another boards in the
system. The part of this connector is redundat power supply creating from two
independet power branche. The next is communication interface QSPI for transport
bigger mount of the data as images from camera. The last communication intefaces
on this connector is CAN bus and after manage communication the board can use
RS-458 bus.


The part of the board is communication beacon which transmitting basic
information about satellite (GPS coordinates, batery status, mission status,
etc.). The message of the beaceon is repeating in the loop with actual data. This
part must be place in the satellite and it is created using open-source
implementation OpenLST. Second communication is GPS receiver, which is define the
position of the satelite and sending this data to flicght controler board. The
last implemented wireless communication is nRF technology, which allow to
transmit images from the satelite demostrator.
