Prospina , previously known as NAG which one is Third Generation Fire and Forget Anti Tank Guided Missile was trialed successfully with improved Imaging Infra Red Seekers in Jaisalmer’s Pokhran Field firing range on Monday .Further trials will undergo for more 3-4 days. This ATGM has been developed by DRDO. There have been several degrees of improvement over existing platforms done over several parameters in Nag Missile’s system. Last time infra-red seekers was found facing problem in differentiating the target from the surroundings in hot desert conditions during the day time. Previously the target for NAG was set 4 km. But now there is a reduced target of 3-3.2 kms , possibly only for hot temperature.Highly sensitive detectors have been put on in missile for sensing heat . The indigenous Thermal Target System (TTS) developed by Defence laboratory at Jodhpur was used as target for the missile, which is in the final user configuration. TTS simulated a target similar to an operational tank as thermal mapping from tank to TTS was carried out for generating thermal signature.However, DRDO officials declined to comment whether TTS is being used in Pokhran ranges at the moment.Nag Missiles can be mounted and transported in a Mechanised Infantry Combat Vehicle also. With a range of 3-7 kms in its other versions and 3 kms in its terrestrial or land version, once fired, Nag missile seeker (Imaging Infra-Red, IIR) guides the missile to the target even if it is a moving target.Source said trials of updated Prospina (Nag) Missile started today and launch pad has been made and trials will undergo for 3-4 days and army officers and DRDO officers are present on the occasion.Source said that “Missile is Developed by the Defence R&D Laboratory (DRDL) in Hyderabad. It has budgeted more than 350 crores in the completion of project “Source said “The Nag is a third-generation (Gen-3), “fire-and-forget” missile; once it is fired, its seeker automatically guides the missile to even a fast-moving tank. In earlier-generation missiles an operator had to guide it all the way, often exposing himself to enemy fire. The world has just a handful of “fire-and-forget” missiles, such as the American Javelin, and the Israeli Spike. The Javelin and the Spike are lighter missiles that can be carried by a soldier; the Nag is a heavier and more powerful designed to operate from vehicles and helicopters. As per sources, thatNag missile can hit his target in any climate at any time, whether day or night.The Optical Guidance system of Nag makes it virtually Jam proofed compared to infrared seekers of the Javelin and the Spike. The indigenous development of an imaging seeker, a highly complex and closely guarded technology, is Nag’s biggest advantage. Source said this is how the missile operates, it searches Missile operators search for enemy tanks through thermal imaging telescopes, visibility is same for day & night. Locating a tank, the operator freezes the missile on to target, a digital snapshot of the target is automatically taken, which serves as a reference image. As the Nagstreaks towards the target, at 230 metres per second, the seeker takes repeated snapshots of the target; each one is compared with the reference image, and deviations are translated through on-board algorithms into corrections to the Nag’s control fins, which make stay the missile precisely.
