HP920 GNSS Receiver – Dual Antenna RTK Positioning and Heading System

High-Precision GNSS Positioning for Professional Applications

The HP920 GNSS Receiver is a high-precision positioning and orientation system designed for applications where reliability and accuracy are critical. It combines dual-antenna GNSS technology, inertial navigation (INS), and multi-network communication in a single integrated device.

The system supports GPS, BeiDou, GLONASS, Galileo, and QZSS, ensuring stable positioning performance across different regions and operating environments.

HP920 is widely used in marine navigation, construction machinery control, and precision agriculture systems, where continuous and accurate positioning is required.

Why Choose the HP920 GNSS Receiver

Accurate Heading Without Movement

The dual-antenna design allows the receiver to determine heading without relying on movement.
This is essential for marine vessels and stationary platforms.

  • Heading accuracy: <0.3° RMS
  • Initialization time: <5 seconds
  • Reliability: >99.9%

Stable RTK Positioning Performance

The HP920 supports RTK positioning via NTRIP or radio correction services, delivering centimeter-level accuracy.

  • RTK accuracy (horizontal): ±(8 + 1×10⁻⁶ × D) mm
  • RTK accuracy (vertical): ±(15 + 1×10⁻⁶ × D) mm
  • Update rate: up to 20 Hz

Multi-Constellation GNSS Tracking

The receiver tracks all major GNSS constellations simultaneously:

  • GPS
  • BeiDou
  • GLONASS
  • Galileo
  • QZSS

This improves positioning reliability, especially in environments with partial signal obstruction.

Built-in INS for Continuous Operation

The integrated 6-axis inertial navigation system helps maintain positioning and orientation when GNSS signals are temporarily unavailable.

This is particularly useful in:

  • Urban environments
  • Marine structures
  • Areas with signal interference

Flexible Communication Options

HP920 supports multiple communication methods:

  • Built-in 4G module
  • Radio communication
  • NTRIP protocol
  • eSIM support for CORS networks

These features enable real-time RTK correction access worldwide.
