Analiza zmogljivosti drona pod vplivom motilca signala GPS

Pistotnik, Gašper (author), Trček, Denis (mentor)

Diplomska naloga se osredotoča na analizo zmogljivosti drona, ki deluje pod vplivom motilca signala GPS. Signal GPS je pomemben dejavnik pri pravilnem delovanju drona, vendar je zaradi vrste razpoložljivih cenovno dostopnih motilcev lahko hitro izpostavljen nevarnostim. Glavni cilj naloge je bil izdelava Faradayeve kletke, ki blokira L1 signal GPS in testiranje ter analiziranje njene učinkovitosti na zmogljivost drona. Vsa testiranja so bila opravljena na brezpilotnem letalniku DJI Phantom 3 Standard, ki je namenjen predvsem zračnemu fotografiranju in snemanju. Za testiranje drona ga je bilo najprej potrebno pripraviti oziroma predelati tako, da se je Faradayeva kletka postavila okoli sprejemnika signala GPS. Pred namestitvijo kletke sta bila sprejemnik GPS in dron testirana za lažjo primerjavo med delovanjem drona pred in po namestitvi kletke ter analizo vplivov na funkcionalnost drona. Za testiranje zmogljivosti drona so bile testirani različni scenariji, kot so testiranje v statičnem okolju, samodejno vzletanje in pristajanje, sledenje točkam (Waypoint), funkcija RTH (Return To Home - vračanje domov) ter način sledenja (Follow Me). Rezultati testiranj in analize so pokazali, da je motilec signala GPS vplival na delovanje drona, kar je privedlo do omejenega nadzora nad dronom.

• Title: Analysis of drone performance under the influence of a GPS jammer

Abstract

The diploma thesis focuses on the performance analysis of a drone operating under the influence of a GPS jammer. The GPS signal is an important factor in the proper operation of a drone, but due to the range of affordable jammers available, it can be quickly exposed to hazards. The main objective of the thesis was to build a Faraday cage that blocks the L1 GPS signal and to test and analyze its effectiveness on drone performance. All testing was carried out on a DJI Phantom 3 Standard drone, which is primarily designed for aerial photography and filming. To test the drone, it first had to be prepared or modified by placing a Faraday cage around the GPS receiver. Before installing the cage, the GPS receiver and the drone were tested to facilitate a comparison between the drone's performance before and after the cage was installed and to analyse the effects on the drone's functionality. To test the performance of the drone, different scenarios were tested, such as testing in a static environment, automatic take-off and landing, Waypoint tracking, Return To Home (RTH) function and Follow Me mode. The results of the testing and analysis showed that the GPS jammer had an impact on the drone's performance, resulting in limited control of the drone.
