HP920 Marine GNSS Positioning System-Dual Antenna RTK Receiver for Marine Navigation and Heading

Built for Reliable Marine Positioning

The HP920 is a dual-antenna GNSS receiver engineered specifically for marine navigation, vessel heading, and high-precision positioning. It is designed to operate reliably in offshore and nearshore environments where stability, accuracy, and continuous operation are critical.

Unlike conventional single-antenna GNSS systems, the HP920 provides true heading output without relying on vessel movement, making it suitable for both dynamic and stationary marine applications.

Traditional GNSS receivers calculate heading based on movement (course over ground), which introduces errors at low speeds or when stationary.

The HP920 solves this limitation through a dual-antenna architecture:

• Real-time heading calculation independent of motion
• Stable orientation for slow-moving or drifting vessels
• Improved safety and control in confined waterways
• Accurate alignment for autonomous systems

This is particularly important for:

• Hydrographic survey operations
• Autonomous surface vessels (ASVs)
• Port and harbor maneuvering
• Offshore engineering platforms

The HP920 is optimized for both heading accuracy and RTK positioning performance.

• Accuracy: < 0.3° RMS
• Initialization time: < 5 seconds
• Initialization success rate: > 99.9%

• Centimeter-level positioning with correction input
• Multi-constellation tracking (GPS, GLONASS, Galileo, BeiDou)
• Stable performance in challenging signal environments

This level of performance ensures consistent and repeatable results, even under wave motion and signal fluctuation conditions.

Marine operations often require uninterrupted correction data. The HP920 integrates multiple communication options to ensure redundancy and flexibility:

• 4G LTE network connectivity
• Built-in radio transmission (UHF optional)
• NTRIP client support
• eSIM capability for global deployment

This multi-channel communication design allows seamless switching between correction sources, reducing downtime and maintaining positioning accuracy.

Marine equipment must withstand saltwater corrosion, humidity, and extreme weather. The HP920 is designed accordingly:

• IP67-rated enclosure (dustproof and waterproof)
• Anti-corrosion housing for long-term marine exposure
• Wide operating temperature range
• Shock and vibration resistance

The system maintains stable performance in offshore, coastal, and inland water environments.

The HP920 is designed for straightforward deployment:

• Standard marine mounting interfaces
• Compact and lightweight structure
• Plug-and-play integration with onboard systems
• Support for common marine communication protocols (NMEA)

It can be easily integrated into existing navigation, control, or data acquisition systems.

Provides accurate positioning and heading for safe navigation in coastal and inland waters.

Supports precise bathymetric surveys and mapping tasks requiring stable heading and RTK positioning.

Delivers reliable positioning and orientation data for unmanned navigation and control systems.

Used in buoy systems, environmental monitoring, and offshore observation stations.

Ensures accurate positioning for construction vessels and floating platforms.
