Automatizace astronomického určování polohy

Automation of astronomical positioning

habilitation thesis

Czech

The work is focused on astronomical positioning as a part of astronomical determination of vertical deflections. Several aspects of the topic are discused. The introduction discuse contemporary instumentation available, its capabilities and main deficiencies. The available instrumentation is regarded as not really satisfactory for modern tasks. As a consequence of previus conclusion, new measuring system for astronomical positioning is proposed, completed and tested by the author. The system is designed for field observations and named Mobile Automated Astronomical System (MAAS). The new measuring system offers several advantages as a high productivity of measurements, mobility and a fully automated and person independent observations. First existing specimen of the measuring system – MAAS-1 was employed in several experimental projects –Veveri Network, AGNES network and Profile Velka Bites – Brno – Uherske Hradiste. All of the projects were focused on quasigeoid determination. The results are discused in the second part of the work. MAAS-1 was thoroughly tested with highly satisfactory results. The system was found to be reliable, user friendly and without significant faults. It’s results were compared with results of several other precise astrogeodetic instruments (notably cirkumzenital 100/1000 and digital zenith camera TZK2-D). External accuracy of results - vertical deflections components – was found to be somewere between 0.2 - 0.3 for standard one hour field observation.
