“…A positioning technique from the carrier-phase measurements that removes or models GNSS system errors to provide a high level of position accuracy from a single receiver is known as precise point positioning (PPP) [5][6][7]. In geodesy, the method is used mostly in post-processing since the time necessary to move from a float to a fixed solution is extended and the convergence can take several tens of minutes.…”

Understanding the factors that might intentionally influence the reception of global navigation satellite system (GNSS) signals can be a challenging topic today. The focus of this research is to evaluate the vulnerability of geodetic GNSS receivers under the use of a low-cost L1/E1 frequency jammer. A suitable area for testing was established in Slovenia. Nine receivers from different manufacturers were under consideration in this study. While positioning, intentional 3-minute jammings were performed by a jammer that was located statically at different distances from receivers. Furthermore, kinematic disturbances were performed using a jammer placed in a vehicle that passed the testing area at various speeds. An analysis of different scenarios indicated that despite the use of an L1/E1 jammer, the GLONASS (Russian: Globalnaya Navigatsionnaya Sputnikovaya Sistema) and Galileo signals were also affected, either due to the increased carrier-to-noise-ratio (C/N0) or, in the worst cases, by a loss-of-signal. A jammer could substantially affect the position, either with a lack of any practical solution or even with a wrong position. Maximal errors in the carrier-phase positions, which should be considered a concern for geodesy, differed by a few metres from the exact solution. The factor that completely disabled the signal reception was the proximity of a jammer, regardless of its static or kinematic mode.

“…V prvem primeru uporabljamo programski paket Bernese GNSS Software, Version 5.2 (Bernese, 2019) (Dach et al, 2015), ki deluje na podlagi dvojnih faznih razlik, torej na relativni način. V drugem primeru uporabljamo programsko opremo lastne izdelave (Oddelek za geodezijo UL FGG), program gPPP, ki deluje po načelu metode Precise Point Positioning (PPP), torej na absolutni način (Sterle et al, 2014;Sterle, 2015). Oba postopka obdelave temeljita na najkakovostnejšem modeliranju sistematičnih vplivov in pogreškov v opazovanjih GNSS, zato zagotavljata rezultate z visoko stopnjo kakovosti.…”

Nowadays, both in the Russian Federation and in foreign countries, the use of global navigation satellite systems (GNSS) for solving various applied problems is an extremely popular solution. Taking into account the current level of development of satellite radio navigation systems, ordinary users have been able to determine their position with a sufficiently high accuracy. However, some tasks require the use of high-precision equipment of geodetic class. Such equipment allows obtaining navigation solutions with an accuracy of better than 10 cm. Unfortunately, the cost of navigation-class navigation equipment is extremely high. Specialists working in the field of satellite navigation are particularly interested in the possibility of using mass-produced GNSS modules to obtain high-precision navigation solutions. In this paper, the possibility of such an application will be considered, taking into account the results of laboratory tests of a mass-produced navigation module.
