GPS – Swiss Jamming Trials

on May 1, 2018 from 6:00 PM to 7:30 PM

Speaker Heinz Wipf of AirNavConulting
Topic Info

GPS – Swiss Jamming Trials

Jamming of GPS is an important aspect of modern navigation system. A presentation about a live test of the effects of jamming on airborne platforms is given.
Real live jamming trials allowed studying the in-channel RF-interference susceptibility of GNSS navigation capabilities in airborne aircraft. While emitting 200mW EIRP from a ground based jammer against L1-C/A signals of visible GPS SV's, all trial aircraft flew an approach like trajectory on an elevated mountain range plateau in Switzerland. For the first time, rotary/fixed wing and civil/military aircraft had a chance to investigate their performance in a realistic jamming scenario. All aircraft had to carry recording equipment so as to allow for an analysis of aircraft behavioral data, ranging from RX C/No to flight management data.
Elaboration of the motivation, experimental set-up, performance assessment, and show-stoppers is presented.
