Tactical-Grade Navigation Systems
High-Accuracy Navigation, Position and Orientation for Defence, UAVs, Robotics and Long Missions
Tactical-grade navigation systems use very stable inertial sensors together with strong GNSS and filtering software. Because of this, they can deliver reliable position, orientation, velocity and heading data even when conditions change fast.
Metromatics supplies tactical-grade navigation systems for defence, autonomous vehicles, high-performance UAVs, marine platforms and mission-critical robotics. These systems stay accurate during vibration, quick movement and short GNSS dropouts. As a result, they are trusted in situations where reliability and precision are very important.

What Makes a Navigation System “Tactical-Grade”?
Tactical-grade systems include higher-quality sensors than standard units. For example, many systems offer:
- Ultra-low drift gyroscopes
- High-stability accelerometers
- Advanced extended Kalman filters
- Dual-antenna GNSS for true heading (when supported)
- Rugged housings for tough environments
Because of these features, tactical-grade systems stay stable during:
- Long missions
- Strong vibration
- Fast movement
- Short GNSS dropouts or interference
Key Benefits of Tactical-Grade Navigation
- Very low drift over long periods
- High accuracy for roll, pitch, yaw and heading
- Fast updates for control systems
- Reliable performance during motion and vibration
- Better heading accuracy with dual-antenna GNSS
- Stable navigation in complex environments
Types of Tactical-Grade Navigation Systems
Tactical-Grade GNSS/INS Units
These systems combine strong GNSS receivers with very stable inertial sensors. Because of this, they deliver accurate position, velocity and orientation.
Dual-Antenna Tactical Navigation Systems
These systems use two GNSS antennas to calculate true heading without magnetometers. As a result, they offer more stable heading in areas with magnetic noise.
Tactical-Grade AHRS
When position data is not required, tactical-grade AHRS units provide reliable roll, pitch, yaw and heading for demanding projects.

FAQ’s About Tactical-Grade Navigation
Q1. How is tactical-grade different from industrial-grade?
Tactical-grade systems use lower-drift sensors and offer higher accuracy for long missions. Because of this, they are better for defence and other important tasks.
Q2. Do tactical systems work without GPS?
Yes. They can still provide orientation using inertial sensors. However, GNSS is needed for long-term position accuracy.
Q3. Why is dual-antenna GNSS helpful?
Dual antennas give true heading without magnetometers. As a result, heading stays stable in magnetic interference.
Q4. Are tactical systems good for UAVs?
Yes. Many tactical systems are light, rugged and built for high-speed UAV operations.
