  3. 2. Error Injection Study for a SpaceFibre In-Orbit Demonstrator

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Abad Garcia; [2020]
    Nyckelord :;

    Sammanfattning : The space electronics sector is shifting towards the New-Space paradigm, in which traditional space-quali_ed and expensive components and payloads are replaced by commercial o_-the-shelf (COTS) alternatives. This change in mentality is accompanied by the development of inexpensive cubesats, lowering the entry barrie in terms of cost, enabling an increase in scienti_c research in space. LÄS MER

  4. 3. Design and Development of a CubeSat Hardware Architecture with COTS MPSoC using Radiation Mitigation Techniques

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Siddarth Vasudevan; [2020]
    Nyckelord :Commercial Off-The-Shelf Multi-Processor System on Chip; Single-Event Upset; Single-Event Latch-up; Cyclic Redundancy Check; Scrubbing; Radiation hardened Micro-Controller Unit; Soft Error Mitigation-Intellectual Property controller; Error Injection; Space packet protocol; NOR Flash; Magnetoresistive RAM;

    Sammanfattning : CubeSat missions needs components that are tolerant against the radiation in space. The hardware components must be reliable, and it must not compromise the functionality on-board during the mission. At the same time, the cost of hardware and its development should not be high.

  5. 4. Embedded Computer for Space Applications suitable for Linux

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Johan Dahlberg; [2003]
    Nyckelord :Datorteknik; Embedded computer; Space; Linux; Radiation; Single event upsets; Error correction; Hamming codes; Microprocessor; Memory; StrongARM; FPGA; Datorteknik;

    Sammanfattning : This report briefly describes the special requirements for a computer board for use in space. In particular, component selection and ways of mitigating the soft and hard errors are discussed. Furthermore, one implementation for a low-cost, relatively high performance computer that will work in the harsh space environment is presented. LÄS MER
