Low-cost Remotely Operated Underwater and Unmanned Aerial vehicles: new technologies for archaeo-geophysics

Lecce

In this paper we present a device for
magnetic survey devoted in particular for
archaeological purposes. The device is able to perform
accurate measurements of the total magnetic field, it is
a flexible device, programmable by the users to be
suitable for any specific need. The device relies upon
microcontroller, a digital three axes Fluxgate
magnetometer, a GPS, and a Real Time Clock (RTC)
module. The device is compact and lightweight to be
assembled on aerial and marine drones. Recently,
Remotely Operated Vehicles (ROV) and Unmanned
Aerial Vehicles (UAV) gained great potential for
archaeo-geophysics because of their versatility and
low cost, therefore the magnetometer represents a
very useful tool for fast and reliable measurements.
