Engineering specialized equipment like the digital UXO detection magnetometers and related dataloggers and software requires testing and validation. 

The Gouda UXO-Equipment Digital Triaxial Magnetometer Module was tested and validated on 18th August 2021. This research aimed to determine, in combination with the Stitcher, which objects can be detected and at what distance. For example, the influence of the Stitcher on the data has been determined, as has the effectiveness of the magnetometer module. 

In addition, the advantage of a digital triaxial magnetometer module equipped with a double tri-axial sensor over the digital triaxial magnetometer module with a single tri-axial sensor has been firmly established.

The tests were carried out at the MOB site, Boompjesweg, Landhorst, The Netherlands. This location is also known as the Ammunition Technology Museum (Munitie Technologisch Museum – MTM). At this location, there is a test field where 3 objects are buried at a depth of between 2 and 5 meters. The exact location is known and the 3 locations are marked using GPS coordinates.

The following objects were used for the test:

1. 1000 lbs bomb
2. 500 lbs bomb
3. 100 lbs bomb

These objects have been buried at this location for more than 4 years.

This part of the site and these objects are regularly used to test and validate detection equipment. The terrain is sandy and fairly firm. The geolocation of the objects remains stable and identical since burial. Based on the known GPS coordinates, test points were plotted at 50 cm, 150 cm, 200 cm, 250 cm, and 300 cm from the object.
