The IF4010 is a ruggedised inertial navigation unit built around a closed-loop fibre-optic gyroscope and high-precision quartz accelerometers, engineered for long-term attitude, heading and position integrity without external referencing. Its architecture supports primary navigation roles for large unmanned aerial vehicles (UAVs), unmanned surface vessels (USVs), unmanned submarines (UUVs) and defence platforms operating in contested or GNSS-denied environments. The system integrates seamlessly into high-end avionics, maritime and land-based mission systems where inertial autonomy and resilience are paramount.
Within its sealed enclosure, the IF4010 offers gyro bias stability down to 0.005°/h, accelerometer bias stability in the order of 10 µg and enables inertial-only heading accuracy under sustained operation. It supports multiple interface options (Ethernet, RS-422, CAN) and is qualified to MIL-STD shock, vibration and environmental standards — making it suitable for rugged defence deployment. For system integrators deploying next-generation unmanned platforms or navigation-hardened systems, the IF4010 provides a scalable, high-integrity navigation core that minimises reliance on external aiding while maintaining full mission-critical performance.
Key features include:
- Closed-loop fibre-optic gyroscope with bias stability of 0.005°/h across full operational temperature.
- High-precision quartz accelerometer system achieving accelerometer bias stability of ~10 µg.
- Pure inertial attitude/heading capability: inertial-only heading accuracy maintained for extended durations without external input.
- Ruggedised electronics qualified to MIL-STD/-MIL-STD-810 and IP67/NEMA4X environmental protection.
- Interfaces: RS-422, CAN, Ethernet; output update rates up to 1000 Hz (typical).
- Full temperature range operation: –45 °C to +70 °C, designed for harsh operational theatres.
