Step 1 — Drone Anatomy
What Goes Inside a Drone?
Think of a drone as a flying robot. Just like a car has an engine, gearbox, steering, and fuel tank — every part has a specific job. Here's every component, explained simply.
🦴
Frame (Chassis)
Like the human skeleton
Everything mounts onto the frame. Made from carbon fibre or aluminium. Garuda's Kisan Drone frame is manufactured in India at their Chennai facility.
🌀
Motors (4–8 per drone)
Like a car engine — multiplied
Brushless DC motors spin the propellers. If even one fails, the drone crashes. An agri drone uses 4–6 motors. Currently imported mostly from China.
🪁
Propellers (Blades)
Like helicopter blades
Spinning propellers push air downward to create lift. Made from plastic or carbon fibre. Increasingly being manufactured within India.
🧠
Flight Controller (The Brain)
Like a car's onboard computer
Calculates 400+ times per second which motor should spin how fast to keep the drone stable. Runs on microchips — currently imported. This is India's biggest bottleneck.
⚡
ESC — Electronic Speed Controller
Accelerator pedal for each motor
The Flight Controller sends a command — "give this motor 80% speed" — the ESC executes it. One ESC per motor = 4–6 ESCs per drone. Mostly imported.
🔋
Battery (LiPo / Li-ion)
Like the fuel tank
High-density lithium battery. An agri drone flies only 7–15 min because it carries 8 kg of liquid + its own weight. Garuda opened its own battery factory in Chennai, January 2026.
📡
GPS + Sensors
Like Google Maps + eyes
GPS tells the drone where it is. Barometer measures altitude. Obstacle sensors detect trees and power lines. Chips imported; integration done in India.
📷
Camera / Payload Sensors
The drone's eyes
RGB for photography, multispectral for crop health, thermal for night ops. High-end sensors sourced from China and Japan — ~65% of imaging components imported.
💧
Spray System (Agri only)
Like a tractor's pump and nozzles
8-litre tank, pump, flow sensors, and 4–6 nozzles for uniform pesticide coverage. Garuda designs and manufactures this in-house — it's a core IP advantage.
📻
Radio Link / Communication
Like a walkie-talkie
2.4–5.8 GHz radio link between the pilot's controller and the drone. Range: 500m–5 km. Chips imported; assembly and integration done in India.
💻
Software / Firmware / AI
The drone's operating system
Garuda builds its own AI/ML software with Tata Elxsi — crop detection, auto-routing, field mapping. 100% made in India. A key competitive moat.
🌐
Ground Control Station
The pilot's cockpit on the ground
Laptop + software where the pilot plans flight paths, monitors live data, and reviews spray logs. Garuda's own proprietary platform.
Step 2 — Supply Chain
What Do They Make vs. What Do They Import?
Garuda's CEO has stated publicly: "Currently 40–45% of components are imported — target is 85% indigenisation within 3–5 years." Here is the full breakdown.
| Component |
Source |
Why |
| Drone Frame (carbon fibre) |
🇮🇳 Made in India |
Manufactured at Garuda's Chennai facility. Basic structural work is feasible in India. |
| Propellers |
🇮🇳 Made in India |
Plastic moulding — Indian vendors are available and cost-competitive. |
| Spray System (tank, pump, nozzles) |
🇮🇳 Garuda in-house |
Custom-designed precision spray system — core IP. Garuda's agri advantage over DJI. |
| Software / AI / Firmware |
🇮🇳 India — Garuda + Tata Elxsi |
Completely indigenous. Creates a data and analytics moat that pure hardware companies lack. |
| Battery Pack |
🔄 Transitioning |
New Chennai battery factory opened Jan 2026. Cells still sourced externally for now. |
| Motors (Brushless DC) |
🇨🇳 Imported — China |
China produces motors far more cheaply and precisely. India currently lacks capacity. |
| ESC (Electronic Speed Controller) |
🇨🇳 Imported — China |
Complex power electronics requiring specialised fabs not yet available in India. |
| Flight Controller (Microchip) |
🇨🇳 🇺🇸 Imported |
Advanced microprocessors — semiconductor fabs don't exist at scale in India. TSMC/Qualcomm chips. |
| GPS Module |
🇨🇳 Imported |
Precision GPS modules (u-blox) — no domestic alternative at required spec. |
| Cameras (RGB, Multispectral) |
🇨🇳 🇯🇵 Imported |
~65% of imaging components still imported. Sony and Omnivision sensors dominate. |
| Thermal / LIDAR / Radar (Defence) |
🇺🇸 🇮🇱 Imported |
Defence-grade sensors for Trishul drone — US and Israel. No domestic alternative. |
| Radio Transceivers |
🔄 Partial |
Chips imported; PCB assembly and system integration done at Garuda's India facility. |
⚠️ Key Risk: Motors, ESCs, and flight controller chips all come from China. If China restricts exports (as has happened with semiconductors), Garuda's production lines could stall. This is why India's drone indigenisation policy matters — and why Garuda's battery factory is strategically important.
✅ Garuda's Moat: The spray system design, software/AI stack, pilot training ecosystem, and DaaS service delivery are all built in India. DJI does not have anything close to this depth of agricultural infrastructure on Indian soil.
Step 3 — Inside the Factory
How Is a Drone Assembled?
Garuda operates a 24,000 sq. ft. manufacturing facility in Chennai. In 2025, a second facility was added — effectively doubling production capacity. Here is how one drone goes from raw parts to a finished, flyable product.

Cost Mix FY25 (₹100.9 Cr)
What the Numbers Actually Tell Us
| Insight | Data Point | Implication |
| Hardware surging, Services dipping |
Products: +41%. Services: −17% |
Drone sales bouncing back (subsidy push) but service revenue slipped — possibly project delays or competition in DaaS |
| Material cost is the biggest pressure |
₹72.5 Cr — 72% of total expenses |
China-imported components rising fast. Every ₹1 of rupee depreciation vs USD directly hurts margins. Indigenisation is mission-critical. |
| Inventory built up aggressively |
−₹16.6 Cr inventory build vs −₹1.2 Cr FY24 |
They're producing/buying far more than selling. Could indicate pipeline of large orders ahead — or working capital risk if demand softens. |
| Debt almost paid off |
Finance costs down 40% to ₹1.2 Cr |
Long-term debt: ₹0.48 Cr. Short-term: ₹6.2 Cr. Clean balance sheet — well-positioned for IPO. |
| Other income jumped 773% |
₹7.1 Cr vs ₹0.8 Cr FY24 |
Likely includes government grants, forex gains, or one-time items. Inflates total income — operating revenue tells the real story. |
| Ad spend rising fast |
Advertising/Promo: ₹11.3 Cr (↑70%) |
Heavy spend on brand/marketing — MS Dhoni campaigns, Aero India presence, DaaS customer acquisition. Investment phase, not waste. |
| Trade receivables high |
₹114.8 Cr — 97% of annual revenue |
Almost 1 year of revenue sitting unpaid. Government/PSU customers tend to pay slowly. This is the single biggest working capital red flag. |
⚠️ Biggest Red Flag from the Filings: Trade receivables of ₹114.8 Cr against revenue of ₹117.7 Cr means nearly a full year of sales is outstanding. Auditors also flagged delays in depositing statutory dues (GST, PF, ESI). For a pre-IPO company, these are items SEBI will scrutinise closely.
Step 5 — Business Model
How Does Garuda Make Money?
Garuda is not just a drone manufacturer — it runs a three-sided business. Think: a company that builds cars, also runs an Ola-style service, AND operates a driving school — all in drones.
🏪
Model 1: Sell the Drone
One-time hardware transaction — ₹59.8 Cr in FY25
A farmer or company buys the drone outright. Price: ~₹5–12 lakh per agri drone. Government SMAM subsidies cover 40–50%. Garuda gets quick cash but the relationship typically ends there.
🔄
Model 2: Drone as a Service (DaaS)
Recurring service contracts — ₹56.2 Cr in FY25
Customer pays for outcomes, not hardware. "Spray my 100 acres." Garuda sends its drone and pilot. Charged ~₹300–500/acre. NTPC, IOCL, NHAI — all on this model. Note: this segment dipped in FY25 — a concern.
🎓
Model 3: Pilot Training (RPTO)
Course fees + pilot supply flywheel
DGCA-certified training costs ₹50,000–1,00,000 per student. These pilots then staff Garuda's DaaS fleet — a powerful flywheel that keeps operating costs lower than hiring from the open market.
💡 Why DaaS Is the Real Prize: With DaaS, the customer doesn't need to understand drones — they just pay for results. This is recurring revenue like a subscription. Yet in FY25, DaaS services actually declined 17% to ₹56.2 Cr, while hardware sales grew 41%. This reversal is the key question for Garuda going into its IPO — can DaaS recover and re-accelerate?
Step 6 — Customer Segments
Who Buys From Garuda, and Why?
🌾
Farmers (Agriculture)
Largest segment — ~55% India market share
1 agri drone = 1 acre in 7 minutes vs. 2 hours by hand. 500+ spray orders via PM Modi's Drone Didi initiative. Government subsidies make it affordable. This is Garuda's core volume driver.
🏭
Government & PSUs
High-value, long-duration contracts
NTPC — power plant inspection. IOCL — refinery surveillance. NHAI — highway mapping. Survey of India — PM SVAMITVA land records. Stable but slow-paying (hence the receivables problem).
🛡️
Defence
Nascent today, massive tomorrow
Trishul border-patrol drone for armed forces. Govt allocated ₹9,400 Cr for indigenous drone defence in FY26. Garuda's Thales partnership (UTM drones) is aimed squarely at this segment.
🏢
Large Corporates
Industrial DaaS clients
Tata, Adani, L&T for infrastructure inspection. Flipkart and Swiggy for delivery trials. None own drones — all use the DaaS model. High contract values, sticky relationships.
Summary
The One-Line Explanation
🚁 Garuda Aerospace = Tata Motors + Ola + Driving School — all built around drones
Like Tata Motors — designs and builds its own products (frame, spray system, AI software)
Like Ola — runs a drone-cab service (DaaS); the drone is Garuda's, the pilot is Garuda's, customer pays per use
Like a Driving School — trains DGCA-certified pilots who then staff its own service fleet
On the supply chain: The brain (chips) comes from China. The body (frame, spray system) is made in India. The soul (software, service) is 100% Indian. And slowly, even the brain is coming home — the battery factory is step one.
The FY25 warning sign: DaaS revenue fell 17% while receivables piled up to ₹114.8 Cr. For a company chasing a ₹1,000 Cr IPO, resolving these two issues is the most important pre-listing task.
