Digital zenith camera VESTA and its applications

2021
<p>The portable digital zenith camera (DZC) VESTA (VErtical by STArs) determines the deflection of vertical (DoV) components as the difference between the direction to the ellipsoidal zenith (calculated from reference star observations, fixing precise time moment and site coordinates) and the direction of the plumb line, which is ...

Digital zenith camera VESTA and vertical deflection test site measurement results

2023
Digital zenith camera (DZC) VESTA (VErtical by STArs) was developed at the University of Latvia and has achieved an accuracy of 0.1 arcseconds.Currently, a detailed analysis of optimal measurement conditions and potential error sources of DZC VESTA is performed.

Simultaneous parallel astrogeodetic observations using two digital zenith camera systems: Comparing CODIAC and VESTA

2023
Nowadays, zenith telescope-based digital zenith camera systems (DZCSs), such as the Compact Digital Astronomical Camera (CODIAC) and VErtical by STArs (VESTA), are used to determine highly accurate astrogeodetic deflections of the vertical (DoVs). The CODIAC and VESTA were developed by ETH Zurich and University of Latvia, respectively, and only two ...

The digital zenith camera as an additional technique for quasi-geoid model determination of Latvia

2020
<p>The digital zenith camera VESTA (VErtical by STArs) was designed by the Institute of Geodesy and Geoinformatics (GGI) of the University of Latvia and completed in 2016. By 2020 more than 400 terrestrial vertical deflection measurements were observed in the territory of Latvia.
