Read the Passage below and answer the question.

The ITR extends 17 km along the seacoast where number of tracking instruments have been deployed along the flight path of the test vehicles. Some of the significant test facilities at the ITR are a mobile and fixed electro-optical tracking system, mobile S-band tracking radar, fixed C-band tracking radar, fixed and mobile telemetry system, range computer, photo processing system, meteorological system and range safety systems. An expert system has been developed or aiding safety decisions during launch. The ITR is slowly but surely growing into a world-class range.

It was a hot and humid midnight sometime in July 1995. We were going through the results of the fourth consecutive successful flight of Prithvi. People's faces were lit up with success. There was a mood of celebration. More than thirty of us, representing 1,200 hard-working team members, were pondering over the question - what next? Lt. Gen. Ramesh Khosla, Director General Artillery, suggested that the Army needed a flight test on a land range with the accuracy of impact at the final destination within 150 meters. This is called Circular Error Probability (CEP) in technical terms.

We started test-firing our missiles from the Sriharikota Range of ISRO but needed our own missile test range. The Interim Test Range (ITR) was established in 1989 as a dedicated range for launching missiles, rockets and flight test vehicles. A number of missiles of different class including the multi-role Trishul, multi-target capable Akash, the anti-tank Nag missile, the surface-to-surface missile Prithvi, and the long-range technology demonstrator Agni have been test-fired from the ITR. BrahMos, the Indo-Russian joint venture set up to develop supersonic cruise missiles, has also been tested at this range. The ITR has also supported a number of other missions such as testing of the multi-barrel rocket launcher Pinaka and the pilotless aircraft Lakshya.

According to the passage, which of the following is NOT included in the test facilities at the ITR?

Infiltration Prevention and tracking system

"Some of the significant test facilities at the ITR are a mobile and fixed electro-optical tracking system, mobile S-band tracking radar, fixed C-band tracking radar, fixed and mobile telemetry system, range computer, photo processing system, meteorological system and range safety systems."

From the above lines of the given passage it is clear that all other options are included in the test facilities at the ITR except Infiltration Prevention and tracking system
