Abstract

U ovom radu razvijena je programska potpora za upravljanje sustavom za prikupljanje podataka o svjetlosnom onečišćenju Zemlje, namijenjena za korištenje na nanosatelitu FERSAT. Dan je pregled prethodnih aktivnosti u sklopu projekta FERSAT. Opisano je postojeće sklopovlje i programska potpora. Opisano je komunikacijsko sučelje SPI (Serial Peripheral Interface) pomoću kojeg komponente senzorskog sustava komuniciraju s mikrokontrolerom. Razvijeni su upravljački programi za prikupljanje senzorskih podataka s analogno-digitalnog pretvornika i temperaturnog senzora. Razvijena je programska potpora za pripremu podataka za daljnju obradu i računanje spektra signala korištenjem FFT (Fast Fourier Transform) algoritma. Razvijena programska potpora integrirana je u postojeću programsku potporu za PDH (Payload Data Handler) računalo, koja koristi operacijski sustav FreeRTOS za ostvarivanje višezadaćnosti.

Abstract (english)

In this thesis a software for light pollution sensors data acquisition subsystem of FERSAT nanosatellite was developed. A brief overview of previous FERSAT project actitivies was provided. The existing hardware and software developed in previous actitivies was described. The SPI (Serial Peripheral Interface) communication interface used for data transfer between sensor subsystem components and microcontroller was described. Device drivers for analog-to-digital converter and temperature sensor were developed. Software for sensor data preprocessing and signal spectrum calculation by means of FFT (Fast Fourier Transform) algorithm was developed. All developed software components were integrated into an existing FreeRTOS based application for the PDH (Payload Data Handler) computer in order to provide multitasking support.
