In English: Star trackers are used on satellites for accurate attitude determination. This thesis focuses on
developing and testing the hardware for the ESTCube-2 star tracker prototype. The workflow
consisted of selecting suitable components, creating a schematic and a PCB layout, assembling
and testing the hardware. The created hardware can take images with an image sensor and transmit
the image data to a computer. Some software was written to ease the testing of the hardware. The
software allows users to control power buses, update the FPGA configuration, configure the image
sensor and view the captured images from a personal computer. The created hardware serves as a
basis for future software development and the creation of the flight model of the ESTCube-2 star
tracker.
Eesti keeles: Tähejälgijaid kasutatakse satelliitide täpse asendi määramiseks. Käesolev bakalaureusetöö
kirjeldab ESTCube-2 tähejälgija prototüübi riistvaraarendust ning selle testimist. Töö käigus valiti
sobivad komponendid, koostati elektriskeem ja trükkplaadi disain, koostati ja testiti tähejälgija
riistvara. Loodud seade on võimeline tegema pildianduriga pilte ja väljastama pildiinfot arvutisse.
Riistvara testimiseks loodud tarkvara laseb arvutist lülitada tähejälgijal sisse/välja toitepingeid,
uuendada FPGA konfiguratsiooni, konfigureerida pildiandurit ning laseb vaadata pildianduri
tehtud pilte. Loodud riistvara on aluseks tulevasele tarkvaraarendusele ja tähejälgija lennumudeli
valmistamisele
