Short summary
Electromagnetic sensors in a drone set-up allow a lot of movability and downscale the cost and risk typically associated with an airborne system. This paper discusses the pros and cons of our newly developed drone-towed sensor system, where we use the controlled-source electromagnetic sensor GEM-2. We conduct six different tests dealing with altitude dependency, temperature drift, transmission frequencies, T and P mode, and drone noise. Additionally, we show a data set collected with the system.
