  1. 1. Improving Dependability of Space-Cloud Payload Processor by Storage System

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Hassan Said; Stephanie Liza Johansson; [2023]
    Nyckelord :Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

    Sammanfattning : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. LÄS MER

  3. 2. Software based memory correction for a miniature satellite in low-Earth orbit

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :John Wikman; Johan Sjöblom; [2017]
    Nyckelord :Software based memory correction; DRAM; Reed-Solomon; Hamming; CubeSat; Low-Earth Orbit; MIST;

    Sammanfattning : The harsh radiation environment of space is known to cause bit flips in computer memory. The conventional way to combat this is through error detection and correction (EDAC) circuitry, but for low-budget space missions software EDAC can be used. LÄS MER

  4. 3. Implementation of a Distributed Fault-Tolerant NoC-based Architecture for the Single-Event Upset Detector

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Eleftherios Kyriakakis; [2017]
    Nyckelord :;

    Sammanfattning : Today, with the rise of the private sector in space exploration, space missions are becoming more frequent than before. This in relation to the fact that modern electronics scale both faster and denser, the effects of radiation become a critical design requirement for fault-tolerance in on-board space computer systems.

  5. 4. Radiation Induced Effects in Electronic Devices and Radiation Hardening By Design Techniques

    Master-uppsats, Linköpings universitet/Elektroniska komponenter; Linköpings universitet/Tekniska högskolan

    Författare :Johan Walldén; [2014]
    Nyckelord :Radiation; Radiation Hardening By Design; RHBD; Displacement Damage; DDD; Total Ionizing;

    Sammanfattning : The aim with this thesis has been to make a survey of radiation hardened electronics, explaining why and how radiation affects electronics and what can be done to harden it. The effects radiation have on electronics in general and in specific commonly used devices are explained qualitatively. LÄS MER
