RLG based INS used in Agni V is Indian developed,as in Agni V & Agni III.
Also that report you posted is plain BS,DRDO has developed alloys & composites used in Indian,missiles on its own.

I know very well that DRDO has had several problems in several projects and have seen the delays ,. ICSIN is pretty credible and is a think tank based in Delhi.
Second.Even defence technology analyst Prasun K. Sengupta would heavily disagree with you(google his article Why Is This DRDO Official In Moscow?)
It now seems that the veil of secrecy surrounding on-going R & D projects involving the K-4 SLBM and the Agni-5 ICBM is slowly being lifted in a deliberate and well-calibrated manner by both Russia and India, although significant firewalls—mandated by Russia—still remain in place. First, there was the first publicised (and the eighth) test-firing of the K-15 ‘Shaurya’ cannistered SLBM from a land-based missile silo on November 12, 2008. This was followed by the launch ceremony of the ‘Arihant’ SSBN on July 26, 2009, following which India and Russia on December 22, 2010 signed an agreement to share high-precision Py-code signals obtained from Russia’s GLONASS constellation of GPS navigation satellites. The latest revelation came on October 4, 2011 in the form of a Ministry of Defence (MoD) press release that not only gave details about the to-be-held 11th Meeting of the India-Russia Inter-Governmental Commission on Military Technical Cooperation(IRIGC-MTC) in Moscow on the same day, but also disclosed the names of top officials representing the Indian side which, in addition to Defence Minister Arackaparambil Kurien Antony, included Defence Secretary Shashikant Sharma; Secretary Defence Production Shekhar Aggarwal; Lt Gen M S Buttar; Air Marshal R K Sharma; Vice Admiral N N Kumar; Director-General Acquisition Vivek Rae; Chairman & Managing Director of Hindustan Aeronautics Ltd, Ashok Nayak; and most notably, the DRDO’s Chief Controller for Missiles & Strategic Systems & ASL Director, Dr Avinash Chander—the official who is directing and supervising the R & D efforts of the K-4 SLBM and Agni-5 ICBM.
While the likes of Dr Avinash Chander and his boss, Dr Vijay Kumar Saraswat have over the past five years spoken extensively in public forums about the indigenous R & D efforts initiated by the ASL for the Agni family of ballistic missiles, both of them have never uttered a word about any kind of progress on the K-4 SLBM front—strongly indicating that the information-denial firewalls mandated by Russia applied not only to the in-country fabrication of the ‘Arihant’ SSBN and its two larger follow-on variants (each of which will be a scaled-down version of the Project 667BDR SSBN designed by St Petersburg-based Rubin Central Design Bureau for Marine Engineering, and will carry eight SLBMs), but also to the Russian ‘mentoring’ of the K-4 SLBM’s R & D efforts. That may well explain why, on one hand, Dr Avinash Chander first disclosed to the BUSINESS STANDARD newspaper in October 2009 that the ASL was indeed working on multiple independently targetable re-entry vehicles, or MIRV for the Agni-5 (he had said: “We have made major progress on the MIRVs in the last two years”
, while on the other, Dr Saraswat had emphatically stated in March 2010 that the DRDO was NOT developing any kind of MIRV-based warheads for any missile. And neither of them have so far said anything about the K-4 SLBM being armed with MIRV-based warheads.

But here’s what can be inferred from various bits of official revelations/disclosures since the late 1990s. Firstly, it was the creation of the BrahMos Aerospace Ltd joint venture in February 1998 between the DRDO and Russia’s NPO Mashinostroyenia that paved the way for ASL to develop—with Russia’s mentoring—a range of avionics and vectronics required for developing both land-launched ballistic missiles and SLBMs. These include the ring-laser gyro-based inertial navigation system (RLG-INS), along with its miniaturised GLONASS GPS receiver incorporating a 12-channel selective availability anti-spoofing module receiver and using digital RS-422/485 databus interfaces, the inertial measurement unit (IMU) utilising an RS-485 digital databus interface, and the on-board digital computer (which have since been built by the DRDO’s RCI). For the road-mobile transporter-erector-launchers, RCI has built a lightweight land navigation system called FINGS (for providing position and north-pointing information) that makes use of three fibre-optic gyroscopes (weighing less than 1kg), three micro-machined silicon accelerometers and a microprocessor. The system senses acceleration and rotation about three orthogonal axes and outputs temperature compensated incremental angles and incremental velocities. Russia’s JSC Concern Granit-Electron continues to supply the BrahMos Block-2 supersonic land-attack cruise missile’s synthetic aperture radar (SAR), which makes use of scene correlation and navigation (SCAN) algorithm for locating and zeroeing in on the target in top-attack mode. Source codes provided by JSC Concern Granit-Electron to BrahMos Aerospace has enabled the latter to upload SAR imagery (obtained from either overhead reconnaissance satellites like the TecSAR or from EL/M-2060P recce pod) of the target on to the missile’s fire-control system. Also provided by Russia (via NPO Mashinostroyenia) is the technology for fabricating hermitically sealed cannisters made of maraging steel, which can ‘cold-launch’ missiles weighing up to 50-tonnes (like the Agni-5).
