Status of the Project on December, 2012

During autumn of 2012 a number of observation sessions were carried out in order to assess properties of zenith camera in different operation modes and find optimal observation methodology . Accumulated experience resulted in additions and adjustments to control and data processing software, some modifications in construction of instrument.

To ensure accurate imaging time registration, CCD matrix exposure delay was measured.  OEM GNSS receiver was prepared for functioning as the source of time and geocentric coordinates for the camera.

SBIG STF-8300 CCD matrix support was integrated in control software, appropriate control algoritms implemented.

A peer-rewieved paper on zenith camera has been prepared and was published in „Geodesy and Cartography”. Reports in 5 international conferences have been delivered.

Turpināts darbs pie Latvijas reģiona geoīda datu apkopošanas un teorētiskie pētījumi par gravimetrisko un vertikāles novirzes datu kombinētu izmantošanu lai varētu interpretēt zenītteleskopa mērījumu rezultātus, izvēlēties mērījumiem piemērotākās vietas. Turpināta GNSS LATPOS un EUPOS-Rīga datu apstrāde ar Bernes programmatūru gravitācijas lauka anomāliju struktūras izzināšanai.
