The case for synthetic training

The world's serious armies have already made the move.

Synthetic training is no longer an adjunct to live exercise. For every peer-level military, it is the primary preparation method — live training validates what simulation has already taught. The Indian Army is writing that chapter now. DefenceVR is the platform.

Why now

Modern war is drone-defined, spectrum-contested and urban. Live training cannot keep up.

  • 01
    Drones decide the fight

    Contested-zone casualties from first-person-view drones have become the defining signature of the modern battlefield. Every soldier now needs drone-awareness training — whether they fly, defend against, or operate around them.

  • 02
    Live-fire cannot scale

    An Indian Army infantry battalion cycles through live firing ranges on a calendar. A simulator cycles through a battalion in a week. The gap between 'how often we train' and 'how often we should train' is what simulation closes.

  • 03
    The theatres are unforgiving

    Mountain warfare in Ladakh. Jungle in Manipur. Urban CQB in Poonch. Border surveillance on the LAC and LoC. The conditions that decide outcomes are the conditions hardest to replicate in live training.

  • 04
    Lessons in real time

    Ukraine, Gaza, Red Sea, Armenia–Azerbaijan. Every month of contemporary conflict rewrites the training curriculum. Simulation is the only way to keep up without deploying to learn.

The simulator library

Five simulators.
The Army's most urgent gaps.

DefenceVR ships five simulators covering the mission profiles the Indian Army trains for most intensively — drone piloting, counter-UAS, EW-contested ops, small-unit infantry combat and border surveillance. Every simulator runs on the same proprietary engine, calibrated against Aonix's in-house sensor hardware.

The aerial trio

Three simulators, one proprietary core.

The flagship aerial family — drone pilot training, counter-UAS command post and EW-contested operations. Every simulator shares a single 28-parameter flight physics engine and a hardware-informed sensor pipeline calibrated against Aonix's in-house mmWave radar and thermal imaging.

SIMULATOR 01 · Aerial · Drone pilot

UDAAN-SIM. drone pilot simulator with physical rc controller.

A VR drone pilot simulator paired with a real RC transmitter over USB-C. The only training experience where stick-feel, throws and expo carry directly from the simulator into the field kit. Thirteen-plus drone platforms across eight Indian theatres built from 30-metre SRTM elevation data — Ladakh to the Northeast, Kashmir to the Thar.

SIMULATOR 02 · Aerial · Counter-UAS

KAVACH-SIM. counter-drone warfare simulator.

A virtual counter-UAS command post for detecting, classifying, tracking and neutralising drone threats — from a single reconnaissance aircraft to a hundred-aircraft swarm. Sensor simulation is calibrated against Aonix's in-house mmWave radar and thermal imaging hardware, delivering physical fidelity that software-only simulators cannot match.

SIMULATOR 03 · Aerial · EW-contested

VAYU-SIM. drone operations simulator for gps-denied, ew-contested environments.

A combat-operations simulator for the conditions that cause mission failure in modern warfare. Trains drone operators to navigate, coordinate and strike under GPS denial, active jamming and a contested electromagnetic spectrum — the baseline of every peer-level battlefield.

The engineering foundation

A platform,
not a skin.

Every DefenceVR simulator runs on a single proprietary core — physics, sensor simulation and deployment architecture built in India, by engineers with hardware lineage in defence sensing. One authority of record across the library.

01 / 03

28-parameter flight physics

Propulsion, battery chemistry, aerodynamics, environmental forces, sensor physics and electronic-warfare effects — independently configured per airframe. A purpose-built platform, not an off-the-shelf game engine dressed in olive drab.

  • Propulsion & battery
  • Aero & environmentals
  • Sensor physics
  • EW effects
02 / 03

Hardware-informed sensor simulation

KAVACH-SIM's radar, thermal and RF signatures are calibrated against Aonix's in-house mmWave radar and thermal imaging hardware. The simulator is tuned by the same engineers who build the sensors it models.

  • mmWave radar reference
  • Thermal imaging reference
  • Edge AI on device
  • Signature library

Deployable anywhere

Standalone field kit on a single VR headset, or PC-tethered for fixed installations. Identical training content, identical analytics, identical doctrine. The simulator goes where the unit goes.

Answers, grounded.

The questions Indian Army formations, procurement officers and defence-tech press most often ask us. If yours isn't here, write to admin@aonix.in.

  • 01

    What is DefenceVR?

    DefenceVR is India's purpose-built combat simulation platform for the Indian Army. It delivers five flagship VR simulators — drone piloting (UDAAN-SIM), counter-UAS (KAVACH-SIM), electronic-warfare operations (VAYU-SIM), section-scale infantry combat (SHAURYA-SIM) and ISR / border surveillance (NETRA-SIM) — plus custom simulation engagements for Indian Army formations. The platform is built by Aonix, headquartered in Giridih, Jharkhand.

  • 02

    Is DefenceVR made in India?

    Yes. DefenceVR is fully indigenous, built on a proprietary simulation engine designed and developed in India. Terrain authoring, threat-library extension and after-action-review analytics all run on Indian infrastructure without foreign-licensor dependencies. The company is registered in India with operations in Giridih (HQ), Patna and Imphal.

  • 03

    Who uses DefenceVR's simulators?

    DefenceVR is built for the Indian Army — infantry battalions, drone pilots, counter-UAS crews, electronic-warfare operators and ISR teams — as well as other Indian armed forces, central armed police forces (BSF, ITBP, CRPF) and Indian defence training schools. The platform supports unit-of-engagement training at section, crew and operator scale.

  • 04

    Which Indian Army problems does DefenceVR solve?

    DefenceVR addresses the gap between live-exercise tempo and the operational realities of the LAC, LoC, Punjab IB, Northeast jungles and high-altitude theatres. Specifically: drone-pilot training at industrial scale, counter-drone decision-loop rehearsal against procedurally varied threats, GPS-denied and EW-degraded mission rehearsal, section-scale CQB / jungle / mountain drills, and border-surveillance ISR operator training.

  • 05

    How does DefenceVR compare to STE, CTTP or Tze'elim?

    Like the US Army's Synthetic Training Environment (STE), the British Army's Collective Training Transformation Programme (CTTP), the IDF's Tze'elim and Singapore's SAF synthetic infrastructure, DefenceVR is platform-scale rather than per-system. It differs in being indigenous to Indian operational geography — Ladakh, Tawang, Punjab IB, Manipur — and built around problem statements articulated by serving and retired officers of the Indian Armed Forces.

  • 06

    What is the technology behind DefenceVR?

    DefenceVR runs on a proprietary in-house simulation engine that models terrain, RF propagation, sensor signatures, adversary behaviour and crew-coordination dynamics. Hardware integrations include standalone VR headsets, weapon-mounted inertial trackers and a physical RC controller that matches Indian Army field drone kit. Instructor tools allow havildar-rank personnel to author scenarios without vendor escalation.

  • 07

    How does the Indian Army procure DefenceVR?

    DefenceVR engages through iDEX problem statements, ADITI deep-tech tracks, DRDO TDF, and direct MAKE-II procurement bids where applicable. On-site demonstrations are available for Indian Army formations, procurement officers and training schools — the team deploys the kit to the requesting location with full theatre library and instructor briefing. Contact admin@aonix.in.

  • 08

    Is DefenceVR available for export or only for India?

    DefenceVR's primary mandate is the Indian Army and other Indian armed forces. Friendly-foreign engagements aligned with Indian defence-export policy are evaluated on a case-by-case basis. The product is built to Indian operational requirements first.
