The Ministry of Defence in a Press release indicated that a Pinaka Missile System developed by Defence Research and Development Organisation (DRDO) was successfully flight-tested from the Integrated Test Range, Chandipur off the Odisha coast on 19 December.Importantly the press release indicated that the navigation system of the missile was aided by the Indian Regional Navigation Satellite System (IRNSS).

Guided Pinaka, an INS+GPS guided, canard controlled, precision strike guided artillery rocket system, has been designed and developed by ARDE, Pune, in association with Research Centre Imarat (RCI), Hyderabad; Defence Research & Development Laboratory (DRDL), Hyderabad; HEMRL, Pune and Proof and Experimental Establishment (PXE), Balasore.

A salvo test was also held on 20 December

India’s indigenous navigation system the Indian Regional Navigation Satellite System (IRNSS) :NavIC is based on seven satellites. IRNSS-1A, 1B, 1C, 1D, 1E, 1F and 1G were launched by PSLV. The NavIC was partially operational as one of the satellites IRNSS – 1A had developed problems in the atomic clock. However, IRNSS-1A is still being used for messaging services.

The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.

The rocket system has a capability of engaging targets in 20 km to 80 km range with accuracy of < 60 m at all ranges. The technical trials of the system were conducted during 11-12 March 2019. Pinaka is an all weather, indirect fire, free flight Artillery rocket capable of engaging enemy up to a range 38 km. It can neutralize an area of 1000x800m in a short period of time with salvo firing. The Indian Army has two Pinaka  regiments with two more sanctioned for induction.  A Pinaka Regiment comprises of three batteries of six launchers each. Each launcher is capable of firing 12 rockets within 45 seconds. Thus theoretically a battery can fire a devastating 72 rockets in a minute completely pulverising the depth area.

The trial was conducted under the supervision of Director RCI Shri BHVS Narayana Murthy, Director ARDE Dr V Venkateswara Rao, Director ITR Dr BK Das, and Director PXE Shri DK Joshi. Secretary Department of Defence R&D and Chairman DRDO Dr G Satheesh Reddy congratulated the teams involved in the flight trial.
