Assume denial
Jamming and spoofing are treated as the operating environment, not an edge case. Every subsystem is designed to degrade gracefully — and navigation is designed not to degrade at all.

Autonomy for
the contested sky
We develop aerial systems and navigation technology engineered to keep operating where satellite signals cannot be trusted — through jamming, spoofing, and complete signal denial.

SCROLL
Mission
The systems that matter are the ones that keep working when the environment turns hostile.
Electronic warfare has made satellite navigation a liability at the exact moment it is needed most. Platforms that depend on it inherit that fragility.
We design for denial as the baseline condition — building aircraft and autonomy software that perceive the world directly, decide onboard, and complete the mission without asking the sky for permission.
Approach
How we build
Autonomy at the edge
Perception, navigation, and state estimation are computed onboard the aircraft, in real time. The platform does not depend on a persistent link to stay oriented.
Sovereign by design
The airframe, autonomy stack, and ground systems are designed end-to-end in-house in India — full ownership of the technology, the supply chain, and the roadmap.
Systems // PRATAP
PRATAP
A man-portable, canister-launched aerial system built for precision engagement in signal-denied environments.
PRATAP is carried by a single operator and launched from a compact canister in the field. Once airborne, it navigates and holds station using onboard sensing alone — no satellite fix required — and carries a modular payload bay that reconfigures to the mission.
System in active development. Details available under briefing.

Autonomy // DRISHTI
Navigation that
doesn't listen to satellites
DRISHTI is our visual-inertial navigation engine. It fuses what the aircraft sees with what it feels — camera and inertial sensing, resolved onboard into a continuous estimate of where the platform is and where it is heading. There is no satellite in the loop, so there is nothing to jam.

Build for the moment
everything else fails
We're a small team building the autonomy, flight, and edge-intelligence stack from first principles — engineered for the moments when GPS, comms, and second chances all disappear.

When the mission has to work without the satellite, it starts with a conversation.
