"Reconfigurable space object optical tracking system of GGI – implementation stage", project supervisor, senior researcher Dr.sc.ing. Diana Haritonova. The project objective is to install and configure the optical tracking system of the Institute of Geodesy and Geoinformatics (GGI) and start its exploitation using for positional astrometric observations. The project will facilitate radical changes in the development of the optical system, bring new knowledge and skills to the post-doctoral researcher.

"Investigation on accuracy improvement of automated zenith camera's VESTA deflection of vertical measurements", project supervisor, senior researcher Dr.sc.ing. Inese Varna. The project objective is exploring the potential of new automated digital zenith camera (DZC) VESTA (VErtical by STArs): 1) by testing it in various environments for investigation of anomalous refraction effect; anomalous refraction is the main limiting factor of ground-based astrometric observation’s precision, causing irregular angular displacements of observed stars; 2) performing accuracy analysis in test site over 2 years to estimate spatio-temporal properties of measured gravitational deflection of vertical (DoV) values.

Laikā posmā no 9. -13. decembrim Amerikas Savienotajās Valstīs, Sanfrancisko ir norisinājies pasaulē lielākais starptautiskais Zemes zinātņu un kosmisko zinātņu forums - AGU Fall Meeting 2019, kurā piedalījušies dalībnieki no 106 valstīm ar ~26000 referātiem. Ģeodēzijas un ģeoinformātikas institūta pētniece Katerīna Morozova ir piedalījusies ar tēmu "Digital Zenith Camera for Vertical Deflection Determination: on the Way to 1 cm Precise Quasi-Geoid Model for Latvia", kas izraisa milzīgo interesi no amerikāņu kolēģiem no Teksasas universitātes, NGS, NGA organizācijām, kā arī citām valstīm (Somija, Dānija, Mongolija utt.). Digitālā zenītkamera ir unikāls instruments, kas izraisa arvien lielāko interesi starptautiskajā līmenī.

GGI director dr. sc. ing. Gunars Silabriedis and lead researcher dr. phys. Ansis Zarins returned back from Louisiana State University, USA, where they led a successful workshop for the colleagues on the deflection of vertical determination using astro-geodetic technique - Digital zenith-camera, presenting both theoretical and practical course. The development of digital zenith camera and data processing software was finished by GGI staff in 2016 and since than arouse  international interest in geodetic society.
