This paper presents the results of a vulnerability test of several geodetic Global Navigation Satellite System (GNSS) receivers in case of intentional signal interference in the frequency L1 for GPS (Global Positioning System). Nine instruments from

Regarding geomagnetic measurements, the impact of the Moon is twenty times smaller than that of the Sun, so it is not easy to determine from daily magnetograms. The influence can be studied after a carefully selected time series of magnetograms obtai

This paper presents the reasons for the establishment, activities prior to and after the construction as well as the first results of coordinate time-series of points of the Slovenian combined geodetic network. The so-called zero-order geodetic netwo

For more than a decade, the GNSS Service at the Geodetic Institute of Slovenia has been managing the national GNSS CORS network SIGNAL, and since 2016 also the GNSS part of the national Zero-Order Geodetic Network. During this period, different probl

In the old coordinate system, church belfries often served as reference points in detail surveying. Consequently, their coordinates were regularly maintained in the geodetic databases of the old coordinate system. Their usability was significantly re

This paper describes GNSS tropospheric impacts, acquired from radiosonde data in Ljubljana over the autumn-winter period in 2017. The tropospheric effect is the same for code and carrier-phase observations and is not frequency dependent. It appears a

In coordinate calculation from terrestrial measurements, the reduction due to the Earth's gravity field should be one of the main topics of consideration. The problem is of extreme importance especially in steep areas, where geoid surface is not para

Tide gauges are used to assess sea level changes. Usually, they are placed on the coast (piers), which can be unstable. Consequently, the vertical movement of the tide gauge should be included in the series of observations. The paper deals with the s

Determination of the mathematical model of elevation computation is based on a discrete data set, which could be used for elevation modelling. Usually, interpolation or approximation techniques are used for function determination. We describe an aspe

In this paper, we present the problem of the increasing pollution of space with the objects that have been sent into space from 1957 onwards. For operating facilities, we describe the use of the two-line Keplerian elements (TLE) for the presentation
