This work analyses possible stochastic models for airborne dual-frequency, multi-constellation (DFMC) GPS and Galileo multipath errors considering their time-correlated nature. The characterization is performed based on flight data collected during the EU project DUFMAN. The potential multipath models are derived as an extension of recently proposed DFMC variance models and we analyse their potential to ensure bounding conditions over time by using frequency domain upper bounding analysis. This paper focus first on the analysis of 100-seconds carrier-phase smoothed code multipath.
