Unmanned aerial vehicles (UAVs) are becoming increasingly autonomous, intelligent, and mission-capable. As missions expand into complex airspace and demand higher reliability, the need for accurate, stable, and redundant navigation methods has grown sharply. Traditional GNSS-only navigation can no longer meet the requirements of high-precision flight, especially in environments where satellite signals are weak, blocked, or intentionally interfered with.
To address these challenges, our company has developed a lightweight, compact, and highly reliable Inertial–Vision–GNSS Integrated Navigation System, designed specifically for UAVs requiring accurate attitude, velocity, and position information during all stages of flight.
Built on our advanced research capabilities in inertial navigation and onboard image processing, the system integrates inertial sensing, visible-light vision processing, and GNSS positioning into one compact module.
This integrated approach ensures:
High-precision navigation under various visibility conditions
Stable autonomous flight even when GNSS performance degrades
Reliable operation throughout takeoff, cruising, and landing
Engineered for UAV platforms, the product features:
Lightweight and compact structure
Low power consumption
High reliability and cost-effective performance
This makes it ideal for small and medium UAVs performing reconnaissance, mapping, inspection, and autonomous landing tasks.
The system provides several advanced onboard capabilities:
Visible-light imaging & onboard image processing
Real-time scene capture and processing for visual feature extraction.
Multi-source integrated navigation
Inertial Navigation
Vision-based Scene-Matching Navigation
Inertial–Vision–GNSS Fusion Navigation
Autonomous Navigation Outputs
Attitude
Velocity
Position
These outputs enable the UAV to complete autonomous missions with high stability and accuracy.
Under normal UAV cruising and landing visibility conditions (visibility >10 km, clear runway or feature targets), the system offers the following performance:
Autonomous Positioning Accuracy:
≤ 100 m (RMS) when operating at 1–5 km flight altitude.
This level of accuracy ensures safe and dependable autonomous landing, even without perfect GNSS availability.
| Parameter | Specification |
|---|---|
| Weight | ≤ 2 kg |
| Dimensions | 170 mm × 142 mm × 116 mm |
| Power Supply | 12 V |
| Power Consumption | ≤ 30 W |
With its compact footprint and low power draw, the system can be integrated into a wide range of UAV platforms without overloading the aircraft.
The UAV Inertial–Vision–GNSS Integrated Navigation System consists of three major subsystems:
Visible-Light Camera Unit
Captures external scenes for feature matching and landing guidance.
Data-Processing Unit
Executes image processing, scene matching, and multi-sensor fusion algorithms.
Inertial Navigation Unit
Provides attitude, angular rate, and acceleration measurements for continuous navigation.
These components work together seamlessly to deliver robust, real-time navigation data.
System dimensions: 170 mm × 142 mm × 116 mm
Weight: ~2 kg
The product supports two installation methods:
Bottom mounting
Side mounting
Each installation surface includes:
Four M4 mounting holes, arranged with a spacing of 134 mm × 60 mm
The UAV airframe secures the device using four M4 screws
This flexible mounting design supports integration with fixed-wing, rotary-wing, and VTOL UAV platforms.
This integrated navigation system is suitable for UAV missions requiring stable and reliable navigation performance, including:
Autonomous takeoff and landing
Long-range or high-altitude cruising
Reconnaissance and surveillance
Power line, pipeline, or maritime inspection
Mapping and photogrammetry
UAVs operating in GNSS-challenged environments
By combining inertial, visual, and satellite navigation techniques, the system offers robust performance even in complex real-world environments.
Our UAV Inertial–Vision–GNSS Integrated Navigation System represents a next-generation solution for intelligent and autonomous UAV navigation. With its compact design, low power consumption, and advanced multi-source fusion algorithms, it ensures precise and stable navigation throughout the entire flight envelope—from takeoff to landing.
If your UAV applications require high reliability, accurate positioning, and strong resilience to GNSS degradation, this integrated navigation system provides a powerful and cost-effective solution.
