OPTOS is a low-cost 3 Unit CubeSat project of INTA (Instituto Nacional de Tecnica Aerospacial). The objective is to demonstrate new technologies in spacecraft development such as:

  • a distributed OBDH (On-Board Data Handling) subsystem based on FPGAs (Floating Point Gate Arrays), and
  • CPLDs (Complex Programmable Logic Devices),
  • an optical wireless communication system (OBCom) with a reduced CAN (Controller Area Network) protocol,
  • the internal structure is based on composite materials
