This paper describes the conceptual design and the implementation of the project of establishing a GNSS control network in the territory of the Republic of Slovenia, which will be used to monitor the quality of the SIGNAL network products and services and to verify the quality of methods and measurement equipment for GNSS positioning. The stabilization process and the selection of locations of GNSS points are described. The determination of the reference coordinates of GNSS points is presented. A comparison of coordinates of the GNSS points in the coordinate reference systems D96/TM and D96-17/TM is made. A comparison of coordinates determined from 24-hour static measurements is also made, by using baselines 1) to the nearest SIGNAL stations and 2) to a virtual reference station (VRS) in the immediate neighbourhood of each point.

The paper presents the empirical use of height movement kinematic model of Earth's crust created for territory of the Croatia, Slovenia and Bosnia and Herzegovina, in order to determine the relative height displacements of crust discrete points between different epochs. Also, presents the use of this model for the purpose of direct levelling measurement reductions determination, from surveying epoch to another unambiguously selected epoch, i.e. in purpose of height movement effects elimination from levelling network node benchmarks. For Croatian territory the quality of the kinematic model is indirectly tested, founded on the comparison of levelling measurement accuracy criteria related to the state II order levelling networks constituted with original and reduced levelling measurements. Levelling lines of two levelling networks of the II order, on the area of two deliberately selected and representative levelling loops of the Croatian state levelling network of I order, were analyzed. An accuracy criterion, using the original measurements and comparatively using the reduced measurements from their survey epoch to the I order network surveying epoch, is determined. Comparative comparison of the original and reduced measurement accuracy criteria is not clearly and unequivocally confirmed, nor completely rejected, the adequacy of the kinematic model quality for measurement reductions determination. However, comparison points to the fact that the quality of the kinematic model enables reliable determination of the relative height displacements at the centimeter level. [ABSTRACT FROM AUTHOR]

The aim of the current bilateral project between CEA Cadarache and JSI is to improve the accuracy of the online thermal power monitoring at the JSI TRIGA reactor. Simultaneously, a new wide range multichannel acquisition system for fission chambers, recently developed by CEA, is tested. In the paper, calculational and experimental power calibration methods are described. The focus is on use of multiple detectors in combination with pre-calculated and pre-measured control-rod-position-dependent correction factors to improve the reactor power reading. The system will be implemented and tested at the JSI TRIGA reactor in 2014. [ABSTRACT FROM PUBLISHER]
