The only Indian micro-drone capable of RTK-assisted precision swarm flight. Made possible by manufacturing our own ultra-lightweight RTK module and flight controller boards in-house. DJI-class performance. Made in India. Fully customisable, upgradeable, repairable.
BUILT IN COLLABORATION WITH AEROSTEM TECHNOLOGIES PVT. LTD.
Every gram is earned. Sub-250g means no DGCA registration required for civilian operation — yet we deliver full RTK precision and swarm capability at this weight.

The same core engineering, configured for four distinct operational domains. Select the variant matched to the mission.
RTK-assisted, 30 high-brightness LEDs, automated launch box, swarm sync software. Designed for corporate events, public celebrations, cultural shows, and large-scale entertainment drone displays.
RTK, mission-ready, swarm coordination AI, no LED payload. The defence variant — payload weight reallocated to mission-critical electronics and coordination AI.
No RTK, FPV camera, manual mode, crash-resistant build. Optional RTK upgrade later. The training variant — designed for the realities of student flying.
Optical flow sensor replaces GPS/RTK for GPS-denied environments. Ideal for indoor training, confined spaces, and environments where GPS is jammed or unavailable.
"No other team in India achieved this in the micro category because of the precision required: we solved it by building our own hardware."
The AeroSpark is not a repackaged foreign drone. It is the result of designing — from first principles — an ultra-lightweight RTK module (AERO A20, 14g) and a compact flight controller (AERO H743) that together enable centimetre-level formation flight in a sub-250g airframe.
This engineering foundation is what separates StellarGen from every other drone company in India.
A step up from AeroSpark FPV. A full-scale training kit that upgrades into a combat platform — without replacing the airframe.
Full FPV and GPS-assisted flight. Return-to-Home, Position Hold, Altitude Hold. Optional RTK. Upgradable into combat platforms — a single frame that evolves with the pilot.
