Acquire
In plain terms: it feels the platform move.
High-rate angular velocity and acceleration from redundant, mission-selected sensor populations.
Technology
Navigation that holds when GNSS doesn't.
We build the onboard system that keeps drones, rockets and satellites knowing exactly where they are — even when GPS is jammed, spoofed or gone.
No satellites, no ground station. Just on-board sensors and software that never stop tracking how the platform moves.
In plain terms
What we actually do.
Close your eyes and you can still tell when you're turning, tilting or speeding up — your inner ear tracks motion without looking. SwiftBird is that sense of balance for a machine.
Tiny sensors feel every rotation and acceleration thousands of times a second. Our software adds all of that motion up, continuously, to keep one answer always up to date: where is the platform, right now? It needs no GPS and no outside signal — so there is nothing an adversary can cut off.
Step 01Senses motion
On-board sensors measure every turn and acceleration up to 6,000 times per second.
Step 02Does the math
The fusion core turns raw motion into clean position, speed and heading in real time.
Step 03Knows where it is
The flight computer always has a position it can trust — with or without satellites.
Why GPS isn't enough
GPS drops. We don't.
GPS is a faint signal from space — it can be jammed (drowned out) or spoofed (faked). The moment it's gone, an ordinary platform is flying blind. SwiftBird keeps it on course to the target.
One navigation chain
From raw motion to an actionable position.
Process
In plain terms: it cleans up the noise.
Proprietary real-time sensor fusion rejects noise, drift and vibration at up to 6 kHz.
Navigate
In plain terms: it works out where you are.
Continuous attitude, velocity and position estimates remain available through GNSS denial.
Control
In plain terms: it tells the autopilot.
Clean, low-latency outputs integrate directly with the flight computer and guidance loop.
Inside the core
Built to survive the electronic-warfare envelope.
Resilience is the whole point. Our fusion core is designed for environments where GNSS is jammed or spoofed and vibration is severe — exactly where conventional navigation degrades.
High-rate estimation, redundant sensing and tight, mission-specific calibration keep attitude, velocity and position trustworthy through denial — and clean enough to drive the guidance loop directly.

Common core
One core, many builds.
Every SwiftBird module shares the same sensing-and-fusion core. So we can build a version tuned to your platform — instead of forcing your platform to fit a product. Tell us the constraint and we build to it.

FAQ
GNSS-denied navigation, in plain answers.
Short answers to the questions teams usually ask before evaluating a compact inertial navigation system for UAVs, rockets or orbital platforms.
What is GNSS-denied navigation?
GNSS-denied navigation means keeping a platform oriented and positioned when satellite navigation such as GPS, Galileo or GNSS is jammed, spoofed or unavailable. SwiftBird uses onboard inertial sensors and sensor fusion so the platform can continue navigating without relying on an external signal.
How does an inertial navigation system work without GPS?
An inertial navigation system measures acceleration and rotation with onboard sensors. SwiftBird processes those measurements with a high-rate fusion core to estimate attitude, velocity and position continuously, even when GPS is unavailable.
Which platforms are SwiftBird inertial navigation systems designed for?
SwiftBird builds compact inertial navigation systems for unmanned aircraft, rockets, high-dynamic vehicles and satellite or near-space applications.
What is the difference between COMPOSITE and ALLOY?
COMPOSITE is the tactical-grade SwiftBird INS for precision-critical platforms. ALLOY uses the same SwiftBird fusion core in a smaller fleet-grade package for scalable unmanned systems.
Does SwiftBird replace GNSS?
SwiftBird does not require GNSS to keep estimating motion, attitude and position, but it can still work alongside external navigation sources when they are available. Each module can also be ordered as a + variant with integrated GNSS. The point is resilience: the platform keeps a navigation answer when outside signals disappear.
Can SwiftBird modules include GNSS?
Yes. Every SwiftBird module can be ordered as a + variant with integrated GNSS, while the inertial core remains designed to keep navigating when GNSS is unavailable, jammed or spoofed.
Where are SwiftBird systems designed and built?
SwiftBird Aerospace designs and builds European navigation hardware in Warsaw, Poland, with a European supply-chain mindset.
