Abstract [en]

The Infrared Spectroscopy to Analyse the middle Atmosphere

Composition (ISAAC) is an experimental module designed by KTH

students. It consists of a Rocket Mounted Unit (RMU) and two

Free-Falling Units (FFU) carried inside. The main objective of the

experiment is to demonstrate ability of one FFU to track the other

and to carry out measurements in cooperation.

This Master’s thesis covers

the development and implementation of

the ejection system as well as data acquisition for the ISAAC

experiment to have well-timed ejection of the FFUs and data for a

post-flight analysis. Ejection control and communication is

implemented in a Field-Programmable Gate Array (FPGA) using

VHDL hardware description language. Newly developed firmware

verification and the post-flight analysis results are also presented in

the report.

The ISAAC experiment was launched on May 29 from Esrange,

Kiruna onboard the REXUS15 rocket.

Abstract [sv]

ISAAC (Infrared Spectroscopy to Analyse the Middle Atmosphere

Composition) är en raketmonterad experimentmodul designad av

studenter på KTH. Modulen består av en raketmonterad modul

benämnd RMU (Rocket Mounted Module), i vilken två mindre


fallande enheter benämnda FFU (Free Falling Units) sitter

monterade. Huvudmålet med experimentet är att demonstrera

förmågan för den ena FFU:n att spåra den andra FFU:n samt

förmågan att genomföra koordinerade mätningar.

Detta examensarbete behandlar utvecklandet och

implementationen av utskjutningssystemet samt datainsamlingen


-experimentet. Dessa delar görs för att kunna genomföra

utskjutningen vid en lämplig tidpunkt samt få data till

efterbehandling. Utskjutningskontroll samt kommunikatio

n är

implementerade i en FPGA (Field Programmable Gate Array) i det

hårdvarubeskrivande språket VHDL (VHSIC (Very High Speed

Integrated Circuit) Hardware Description Language). Verifikation

av nyutvecklad inbyggd programvara samt analysresultat av data

från uppskjutningen presenteras också.

Uppskjutningen av ISAAC-experimentet skedde den 29:e maj 2014

från rymdbasen Esrange i Kiruna ombord på raketen REXUS15.
