## 1 Introduction  
The topic of the paper is important for all geo-activities that are related to surveying land. Globally, in geodesy, we have a control frame and, locally, we have a stated national frame; for current works, we establish networks. Progress in this term was presented in [1], which displays the most important information for practitioners and scientists in the \"Geodesy and Cartography\" field of research. Nowadays, many people use the geo-data, geo-information, or some geo-portals [2], which are produced with reference to control networks. We have many methods of producing land surveying data where geodetic control points play an essential role [3]. As we know, geodetic control networks provide an established national spatial reference system [4]. In modern surveying, the geodetic data are usually realized using space (3D) data obtained from the Global Navigation Satellite Systems (GNSS) methods. Today, in GNSS positioning, six satellite navigation systems are used [5]: GPS of the United States, GLONASS of the Russian Federation, Galileo of the European Union, Compass/Beidou of China, QZSS of Japan, and IRNSS of India. The systems are used together (two or more) to increase the measurement accuracy [6; 7; 8]. There are more space-surveying techniques that can realize the three-dimensional geodetic data by determining or calculating the three-dimensional coordinates of surface points. The applications of geodetic control points are placed in topographic mapping [9], engineering construction measurements [10], and georeferencing survey of point clouds and raster images [11; 12]. According to the classical perspective in surveying, we need reference control points to establish or check equipment (tacheometer--instrument or GNSS--receiver). In these cases, when using new sensors in surveying (UAV--photogrammetry or LIDAR--systems), the control points are helpful for guaranteeing an equal accuracy of produced geo-data [13]. In accordance with national regulation (for example in Poland with Regulation [14]), the base geodetic control network consists of points of the horizontal and the vertical networks. Nowadays, the coordinates of the horizontal (and 3D network) base geodetic control network points mainly are determined using GNSS surveying and the heights of the points are usually determined using geometric precise leveling. The base geodetic control network points are stations of the continuously operating reference system (CORS in Poland named ASG-EUPOS), which established the three-dimensional geodetic data. In the ASG-EUPOS reference network, the average error of the point's position should not exceed 0.01 m and the error of the point's height should not be greater than 0.02 m.  
Generally, in geodesy and especially in surveying topics, the classical method of new applications and modern configurations is used. Photogrammetric flights (raids) for land survey are realized using unmanned aerial vehicles (UAV) from low-altitude distances [15]. Triangulation (directions measurements) may be represented using laser scanning technology [16]. The idea of GNSS surveying can be equated with the implementation of the geodetic intersection task, because the satellite navigation systems are similar to the land-based systems where the satellites act as the reference points [17]. Nowadays, the innovation concept of direct land surveying is the smart station survey, including integrated tacheometric measurements using real-time GNSS positioning, e.g., by Leica [18]. The technology of the smart station surveying was defined by the trends in economic and measurement activity too [19]. Over the last few decades, some innovations in land surveying have been implemented, for example, in establishing the control networks [20,21]. Initially, GPS techniques (currently GNSS technologies) help to eliminate the need for the highest (first) order control point densification and improve the accuracy of control network points [22,23].
