| Zusammenfassung |
| Nowadays many applications and studies use a Global Positioning System (GPS) to integrate
Ground-Penetrating Radar (GPR) data [1-2]. The aim is the production of detailed detection
maps that are geo-referenced and superimposable on geographic maps themes. GPS provides
data to determine static positioning, and to track the mobile detection system path on
the land. A low-cost standard GPS, like GPS-622R by RF Solutions Ltd, allows
accuracy around 2.5 m CEP (Circular Error Probability), and a maximum update rate
of 10 Hz. These accuracy and update rate are satisfying values when we evaluate
positioning datum, but they are unsuitable for precision tracking of a speedy-mobile GPR
system. In order to determine the relative displacements with respect to an initial
position on the territory, an Inertial Measurement Unit (IMU) can be used. Some
inertial-system applications for GPR tracking have been presented in recent studies [3-4].
The integration of both GPS and IMU systems is the aim of our work, in order
to increase GPR applicability, e.g. the case of a GPR mounted on an unmanned
aerial vehicle for the detection of people buried under avalanches [5]. In this work,
we will present the design, realization and experimental characterization of our
electronic board that includes GPS-622R and AltIMU-10 v3 by Pololu. The latter
comprises an inertial-measurement unit and an altimeter. In particular, the IMU
adopts L3GD20 gyro and LSM303D accelerometer and magnetometer; the digital
barometer LPS331AP provides data for altitude evaluation. The prototype of our
system for GPR positioning and tracking is based on an Arduino microcontroller
board.
