High-precision dual-antenna GNSS receiver designed for marine navigation, vessel heading, and autonomous systems. Reliable, stable, and ready for harsh environments.
1. Designed for Reliable Marine Positioning
The HP920 GNSS receiver is engineered specifically for marine environments where positioning reliability and heading accuracy are critical. Unlike standard GNSS receivers used in land surveying, marine applications require stable performance under vibration, multipath reflection, and continuous movement.
The HP920 integrates a dual-antenna design, allowing it to deliver both high-precision positioning and real-time heading information simultaneously. This makes it especially suitable for vessels, unmanned surface vehicles (USVs), and marine monitoring systems.
2. True Heading with Dual-Antenna Technology
One of the most important advantages of the HP920 is its ability to determine vessel heading without relying on movement.
Traditional single-antenna GNSS receivers calculate heading based on motion direction. This approach fails when the vessel is stationary or moving slowly. The HP920 solves this limitation by using two antennas to calculate the baseline vector, enabling:
- Instant heading output
- High stability in low-speed conditions
- Accurate orientation even when stationary
This feature is essential for applications such as:
- Autonomous navigation systems
- Hydrographic surveying
- Marine robotics
- Dynamic positioning systems
3. Stable Performance in Harsh Marine Environments
Marine environments are complex: signal reflections from water surfaces, humidity, salt exposure, and continuous vibration can all affect GNSS performance.
The HP920 is designed to handle these challenges with:
- Multi-constellation GNSS tracking (GPS, GLONASS, Galileo, BeiDou)
- Advanced anti-interference capability
- Robust enclosure for outdoor deployment
- Stable signal tracking under multipath conditions
This ensures consistent positioning accuracy even in ports, coastal zones, and offshore environments.
4. High-Precision Positioning for Professional Applications
For professional users, accuracy is not optional—it directly impacts operational safety and data quality.
The HP920 supports high-precision positioning modes suitable for:
- Marine surveying and mapping
- Dredging operations
- Offshore construction
- Buoy positioning systems
Its positioning performance allows operators to maintain reliable coordinates and heading simultaneously, improving both efficiency and decision-making.
5. Flexible Integration for Marine Systems
The HP920 is designed not just as a standalone receiver, but as a core component of larger systems.
It can be easily integrated into:
- Vessel navigation systems
- Autopilot systems
- Marine monitoring platforms
- Unmanned vessel control systems
With standard communication interfaces and stable data output, it fits seamlessly into existing marine electronics architectures.
