Abstract:Namen diplomskega dela je bil izdelati krmilnik za krmiljenje antenskega sklopa. Krmilnik je namenjen tako avtomatskemu sledenju satelitov kot tudi ročnemu načinu premikanja antenskega sklopa. Krmilnik smo izdelali s pomočjo programskega paketa za načrtovanje elektronskih sistemov Altium designer in okolja za razvoj vgrajene programske opreme CodeVisionAVR. Vgrajena programska oprema je zasnovana v C programskem jeziku. Obstaja že mnogo takšnih sistemov, ki imajo identične funkcije kot jih ima vgrajeni sistem krmilnika za usmerjanje antenskega sklopa. Pri obstoječih sistemih se krmiljenje usmerjanja antenskega sistema izvaja s pomočjo relejev. Slabost uporabe relejev je v tem, da ne omogočajo zveznega sledenja satelitov, mehkega zagona in pospeševanja pri premikanju antenskega sistema. Vgrajen sistem krmilnika za usmerjanje antenskega sklopa bomo krmilili s pomočjo pulzno širinske modulacije. Omejitvi pri načrtovanju krmilnika za usmerjanje antenskega sklopa sta bili napajalna napetost za vezje in aktuatorje, ter kompatibilnost s programsko opremo za sledenje satelitov.
Keywords:vgrajeni sistemi, antenski sklopi, krmilniki, pulzno širinska modulacija, sledenje satelitov.

Title:EMBEDDED SYSTEM BASED CONTROLER FOR DIRECTING THE ANTENNA ASSEMBLY
Abstract:The aim of this thesis was to create a controller for controlling the antenna assembly. The controller is intended for automatic satellite tracking as well as manually controlling the antenna assembly. The controller was developed with the help of the electronic circuit design program Altium designer and microcontroller firmware development software CodeVisionAVR. The controller was programmed in the C programming language. There are already many similar systems, which support similar functions as it does the system presented in this thesis. In existing systems the antenna is moved and directed with the use of electric motors regulated with relays. The disadvantage of using relays is the inability of fluent control of the antenna assembly. Besides you cannot slowly start up and slow down the antenna assembly. The advantage of embedded system based controller for directing the antenna assembly is that we use pulse width modulation for regulating the speed of the antenna assembly movement. The limitations in the controller development stage were the power supply voltage and the compatibility with the software for automatic satellite tracking.
Keywords:embedded systems, antenna systems, controllers, pulse width modulation, satellite tracking.
