FlameVector Tactical IMU

Mission-critical Inertial Navigation System for Autonomous Defence UAV Platforms.

The FBT-IMU-TAC is built from the ground up for the vibration profiles, mounting constraints, and integration needs of modern multi-rotor and fixed-wing drones.

At its core is a factory-calibrated tactical MEMS inertial sensing element, delivered on an open carrier board rather than sealed inside a housing, so integrators can inspect, mount, and adapt it directly into existing autopilot stacks without redesigning around a black box. It ships as a drop-in module for Pixhawk-class flight controllers, using an industry-standard mounting footprint and a locking, keyed connector built for field reliability, not just lab conditions.

It is has been built and tested to work flawlessly, and delivers trusted inertial sensing for defence platforms where navigation performance directly impacts mission success.

Developed around a tactical-grade MEMS inertial architecture, it provides high-fidelity angular rate and linear acceleration measurements required for precision control, navigation and stabilisation.

Target Applications:

1. ISR (Intelligence, Surveillance, Reconnaissance) UAVs

2. Tactical quadcopters and multi-rotor platforms

3. VTOL fixed-wing UAVs

4. Loitering munitions

5. FPV and racing-frame platforms requiring tactical-grade sensing

6. Autonomous ground robotics (UGV)

7. Autonomous surface vessels (USV)

8. Defense R&D and flight-test platforms

9. Counter-UAS and swarm systems requiring GNSS-denied navigation backup

FlameVector TAC IMU delivers high-fidelity six-degree-of-freedom inertial measurements through precision triaxial gyroscopes and accelerometers, fully factory calibrated for bias, sensitivity, axis alignment, g-sensitivity and point-of-percussion effects to maximise measurement accuracy and long-term stability.
