Real live jamming trials allowed studying the in-channel RF-interference susceptibility of GNSS navigation capabilities in airborne aircraft. While emitting from a ground-based jammer on the L1-C/A frequency, all trial aircraft flew an approach like trajectory on an elevated mountain plateau in Switzerland. 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. This allowed an analysis of aircraft data, ranging from receiver C/No to flight management data. Motivation, experimental set-up, performance assessment and showstoppers are elaborated.
