Product Description
Reliable Multi-Constellation GNSS Receiver for Marine Navigation, Engineering Machinery, and Precision Agriculture
HP920 GNSS Receiver is a high-precision positioning and orientation system designed for professional applications requiring reliable GNSS performance in demanding environments.
The receiver integrates dual-antenna GNSS technology, inertial navigation (INS), radio communication, and 4G connectivity into a compact and rugged device. By supporting multiple satellite constellations including GPS, BeiDou, GLONASS, Galileo, and QZSS, the HP920 delivers stable positioning and heading information even in complex operating conditions.
The system is particularly suitable for applications such as marine navigation, autonomous platforms, engineering machinery control, and precision agriculture guidance systems.
Key Advantages
- Dual-antenna GNSS positioning and heading
- Multi-constellation satellite tracking
- Built-in inertial navigation module
- Centimeter-level RTK positioning
- 4G / Radio communication options
- Industrial-grade IP67 protection
Key Features
High Precision GNSS Positioning
The HP920 receiver uses a high-performance GNSS engine capable of tracking multiple satellite systems simultaneously. This improves satellite availability and positioning reliability across different geographical regions.
The receiver supports RTK positioning, enabling centimeter-level accuracy when connected to correction services.
Dual-Antenna Heading Technology
Unlike traditional single-antenna GNSS receivers, the HP920 integrates a dual-antenna system that provides accurate heading information without requiring movement.
This feature is particularly important for:
- Marine vessels
- Autonomous vehicles
- Agricultural machinery
- Engineering equipment
The system achieves a heading accuracy of better than 0.3° RMS.
Integrated Inertial Navigation System
The receiver includes a six-axis inertial navigation module that improves system stability when satellite signals are temporarily blocked.
The INS module helps maintain reliable orientation and positioning information in dynamic environments such as:
- Urban areas
- Dense vegetation
- Under bridges
- Marine structures
Multi-Constellation GNSS Support
HP920 supports major global navigation satellite systems:
- GPS
- BeiDou
- GLONASS
- Galileo
- QZSS
- SBAS
This multi-constellation capability increases positioning reliability and improves accuracy in challenging environments.
Flexible Communication Options
To support different deployment scenarios, the HP920 offers multiple communication methods.
Available communication options include:
- Built-in 4G network module
- Radio communication module
- eSIM support
- NTRIP protocol support
These communication options allow the receiver to access RTK correction data through CORS networks or base stations.
