ABSTRACT:
Performance of GNSS receivers affected by jamming devices
The performance of satellite navigation systems can be affected by well-known error sources and intentional jamming. To improve the jammer detection ability, two measurement events were held in 2015 near Slovenian coast region in agreement with national regulator AKOS and international cooperation team. Several interested groups tested their equipment and made observations under various scenarios of jamming signals presence. This paper provides the description of test area, measurement equipment and focuses on the results of consumer grade uBlox and smartphone GNSS receivers.

POVZETEK:
Obnašanje sprejemnikov GNSS pod vplivom motilnikov
Delovanje satelitskih navigacijskih sistemov je lahko poleg znanih virov napak moteno tudi z namenskimi motilci. Z namenom analize zaznave le-teh sta bila v letu 2015 na območju Primorske v soglasju z AKOS izvedena dva merilna dneva z mednarodno zasedbo. V različnih scenarijih testiranja je več ekip preizkušalo obnašanje sprejemnikov GNSS v mejnih pogojih delovanja v bližini motilca. Prispevek podaja opis izvajanja meritev in merilne opreme, posebnosti testnih tras ter rezultate analize obnašanja nizko cenovnih sprejemnikov GNSS v obliki samostojnih modulov in vsebovanih v mobilnih telefonih.
