Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019).
ESA and NASA conducted a joint Galileo/GPS space receiver experiment on-board the International Space Station (ISS). The objectives (Enderle 2017) of the joint project were to demonstrate the robustness of a combined Galileo/GPS waveform uploaded to

NAECON 2018 - IEEE National Aerospace and Electronics Conference.
In this paper we introduce a model of a node-to-node communication channel as an auto-encoder neural network where the inputs and outputs represent the transmitted and received bits respectively. With some simple assumptions, the encoding layer of th

In this paper we introduce an auto-encoder neural network that can be used to model a node-to-node radio frequency communication channel. With some simple assumptions the encoding layer of this neural network can be interpreted as a phase modulated s
