Abstract

The development of star cameras started in the 1970s. Their purpose was the determination of astronomic position. Using photogrammetric method, the fieldwork could be carried out quickly. The accuracy was reduced compared to the traditional methods, yet the overall time needed for measurement and processing decreased drastically. In the 2000s, some of these instruments were fitted with CCD sensors. Automatized data processing methods were developed, which provided superior speed and accuracy. Recently, the development of a simplified star camera system has been started at the HAS-BUTE PGG. In this paper some key steps of the processing of the measurements are outlined. Many of these steps can be regarded as optimization problems. For this purpose, the Differential Evolution was chosen as a fitting algorithm.
