Abstract [en]

This paper describes work related to the “Miniature Student Satellite” (MIST) project and the ”SiC in Space” project, located at KTH, Stockholm, Sweden. The goal of the MIST project is to launch KTH’s first student satellite into space, carrying multiple scientific experiments where SiC in Space is included.

This thesis contains a compilation of three MIST-related bachelor theses that were carried out at KTH in the spring of 2016, primarily consisting of constructing and testing circuits for power supply and measurements for the SiC in Space part of the satellite.

A printed circuit board has been developed, which accommodates experiment circuits to evaluate the features and functionality of silicon carbide components in a space environment, and power the supply to the SiC in Space and the Piezo LEGS projects. The development includes designing, assembling and testing the PCB according to the MIST team’s demands and requirements.

Emphasis has been laid on electrical safety to ensure that the design can not short circuit the satellite battery, as well as EMC considerations to minimize the EMI between different parts of the satellite. Final testing of the hardware has not been executed due to an ordering error and time shortage, wherefore the planned test protocol has been included for future work.

Abstract [sv]

Denna kandidatuppsats beskriver arbete relaterat till “Miniature Student Satellite” (MIST)-, samt SiC in Space-projekten, vid KTH, Stockholm, Sverige. MIST-projektets mål är att skicka KTH:s första studentsatellit till rymden, där SiC in Space är ett av flera medföljande vetenskapliga experiment.

Detta projekt sammanställer tre examensarbeten relaterade till MIST som genomfördes vid KTH under våren 2016, huvudsakligen bestående av att konstruera och testa kretsar för strömförsörjning samt mätningar för SiC in Space-delen av satelliten.

Ett kretskort som innehåller experimentkretsar för att utvärdera egenskaper och funktionalitet för komponenter av materialet kiselkarbid i en rymdmiljö, samt strömförsörjningskretsar till SiC in Space- och Piezo LEGS-projekten har utvecklats. Utvecklingen omfattar design, montering and testning av kretskortet enligt MIST-gruppens krav.

Tonvikt har lagts på elsäkerhet för att säkerställa att designen inte kan kortsluta satellitens batteri, såväl som EMC för att minimera EMI mellan olika delar av satelliten. Slutgiltig testning av hårdvaran har ej kunnat genomföras på grund av tidsbrist beroende på ett beställningsfel. Därför har det planerade testprotokollet inkluderats för framtida arbete.
