The MIST(MIniature Student saTellite) project is a 3U CubeSat developed by student teams at KTH Royal Institute of Technology in Stockholm. One of the fundamental systems of the satellite is the Attitude Determination and Control System (ADCS), re sponsible for estimating and correcting the satellite’s orientation using magnetic fields and sun sensors. This final degree work belongs to the MIST functional test team. It focuses on building a test environment that verifies that all ADCS components will be have as expected once the satellite is in orbit. This thesis focuses on creating a test framework that can be used to verify the operation of the ADCS. This test framework is composed of several hardware and software components developed to be reliable and flexible, so it can be adapted to verify the behavior of other systems on the satel lite by other teams in the future. The value of this test framework is demonstrated by setting up a HardwareIntheLoop (HIL) simulation of the ADCS in which real flight hardware is used along with other hardware and software components to create a test scenario as close as possible to the orbit. / MIST­projektet (MIniature Student saTellite) är en 3U CubeSat som utvecklats av studentgrupper vid Kungliga tekniska högskolan (KTH) i Stockholm. Ett av satellitens grundläggande system är Attitude Determination and Control System (ADCS), som ansvarar för att uppskatta och korrigera satellitens orientering med hjälp av magnetfält och solsensorer. Det här examensarbetet hör till MIST:s funktionstestgrupp. Det fokuserar på att bygga en testmiljö som verifierar att alla ADCS-­komponenter kommer att bete sig som förväntat när satelliten väl är i omloppsbana. Det här examensarbetet fokuserar på att skapa en testram som kan användas för att verifiera ADCS:s funktion. Testramen består av flera hardware och software komponenter som utvecklats för att vara tillförlitliga och flexibla, så att den kan anpassas för att verifiera beteendet hos andra system på satelliten av andra team i framtiden. Värdet av denna testram demonstreras genom att man sätter upp en HIL­simulering (Hardware­In­the­Loop) av ADCS där riktig flygmaskinvara används tillsammans med andra hardware och software komponenter för att skapa ett testscenario som ligger så nära omloppsbanan som möjligt.

In order to ensure the quality of a product, the provider of the product must performcomplete testing of the product. This fact increases the demands on the test systems usedto conduct the testing, the system needs to be reliable.When developing new software for a company, sometimes a requirements specificationcreated at the beginning of the project is not enough. Details of the desired implementationmay get lost when working with a general requirements specification.This thesis presents a case study of how a certain company work with their test systems.The aim of the case study was to find where the largest points of improvements could bemade in a new test system, which was to be implemented during this thesis work. Theimplementation of this new system was done in LabVIEW in conjunction with TestStandand this process is covered in this thesis.The performed case study revealed that the employees at the company found robustnessand usability to be the key factors in a new test system. During and after the implementationof the new system, it was evaluated regarding these two metrics, this process isalso covered in this thesis.

This work is covering desing of database system which stores results of measerements performed on test stations which are part of assembly line.

This master’s thesis deals with the design and implementation of part of test environment for automatic testing of electronic control unit in the production. The electronic control unit is manufactured by UNIS, a.s. and is used as a control and power electronics for the hydraulic unit. The theoretical part of the thesis deals with the development and automatic testing of electronics in the field of aerospace engineering. The practical part describes the proposed automatic test environment and implementation of testing software using hardware and software products by National Instruments. The main platforms used for software development are LabVIEW and TestStand. Created test environment is finally verified by testing several control units.

The Diploma thesis deals with the testing of turbochargers. Aim of this work is to perform a search on a teststands. Further suggest the teststand's construction. Part of the work is the creation of software for utility measurements available. The program will serve as a basis for checking the measurement data of the turbocharger.
