Introduction
The test site and equipment are the property of HCR-CTRO d.o.o.

The test site was established in 2000 for the purpose of testing hand-held mine detection systems and those mounted on vehicles. With development of advanced technologies, the test site is used for testing of robotic systems, biological detection methods, explosive sensors and airborne detection systems.

Test lanes/areas
The test site is divided into 47 lanes.

1. Blind test lanes (39)  47 m long, 1 m wide, mines are buried at 5-27 cm deep. Distance between the lanes is 3 m. The lanes are divided into 1×1 m squares, their furthermost points are marked. The distance of 3 m between the lanes is sufficient to prevent interference from objects in the neighbouring lanes and to enable passage of a vehicle. There is a 3 m wide area along the fence, and 8 m wide area at the entrance, where the office facility is placed and where preparation and training is conducted.

2. Training and testing lanes with publicly known locations of mines (8 lanes):
Three types of soil:
2 lanes: – neighbouring area soil – uncooperative soil
2 lanes: – soil from the continental part of Croatia – cooperative-neutral soil
4 lanes: – local soil from the test site – uncooperative and heterogeneous

Weather conditions enable the use of the test site all the year round. There is almost no snow or frost, and the rains are rare.

Targets
In the area intended for blind tests there are 810 mines, 449 false alarm objects and 457 empty spaces.

The following types of mines are buried:
– Antitank: TMM-1, TMA-1A, TMA-2A, TMA-3, TMA-4, TMA-5, TMRP-6
– Antipersonnel: PMA-1A, PMA-2, PMA-3, PMR-2A/2AS, PMR-3, PROM-1

The following types of mines are provided for training and testing:
– Antitank: TMM-1, TMA-3, TMA-4, TMRP-6.
– Antipersonnel: PMA-1A, PMA-2, PMA-3, PROM-1

Other types of mines may be provided on users request.

Supporting equipment
There is a weather station at the test site

Security
The test site is protected with a fence and there is a 24 hours a day alarm system.
