2.2.2. The Total Station

A Total Station Leica 1201+ has been used for TLS alignment and control measurements; its main characteristics are reported in Table 2. We note that a low-cost total station can also be used, provided it is equipped with a visible Laser Pointer.



## 2.2.3. The Digital Camera

For the second test, a video of the mobile loads was acquired using a NIKON D610 camera with a 55 mm previously calibrated NIKKOR lens. The main features are shown in Table 3.

## 2.2.4. The GNSS Receiver

The GNSS receiver used for the mobile load of the third test is a Leica GS15, mounted on a strong magnetic base that allows the fixing on the roof of a vehicle. It can provide raw and rinex data and allows a recording rate up to 20 Hz. For our aims, the receiver was configured to track GPS and

GLONASS; the Continuously Operating Reference Station (CORS) of the University of Calabria was used in order to perform the post processing.
