PolyNav 3000A Automotive GNSS/INS RTK Navigation System

High-Precision Positioning | Stable Heading | Reliable Navigation

Product Overview

The PolyNav 3000A is a next-generation GNSS/INS RTK navigation system designed for autonomous vehicles, robotics, mobile mapping, unmanned surface vehicles (USVs), and industrial applications.

Combining dual-antenna, multi-frequency GNSS, an automotive-grade MEMS IMU, and advanced tightly coupled GNSS/INS fusion, it delivers centimeter-level RTK positioning under suitable conditions, stable heading, and continuous navigation during temporary GNSS signal interruptions.

With a compact design, flexible interfaces, and support for system integration, the PolyNav 3000A is built for practical navigation challenges across land and water-based applications.

Key Features

• Centimeter-Level RTK Positioning under suitable GNSS and correction conditions
• Dual-Antenna Heading: 0.08° heading accuracy with a 1 m antenna baseline
• High-Performance IMU: 0.5°/h gyroscope bias stability
• Advanced GNSS/INS Fusion: Supports continuous navigation during temporary GNSS interruptions
• Multi-Constellation GNSS: GPS, GLONASS, Galileo, BeiDou, and SBAS
• Multi-Frequency Support: L1/L2/L5
• High-Rate Output: Up to 100 Hz
• Flexible Interfaces: Ethernet, CAN, RS232, and PPS
• Software Integration: NTRIP, built-in FTP data download, and ROS1/ROS2 drivers
• Compact & Rugged: IP65 protection, operating temperature from -20°C to +70°C, and total weight under 1 kg including both GNSS antennas
• Optional Connectivity: Wi-Fi or LTE, depending on configuration

Real-World Testing & Validation

The product images show actual PolyExplore navigation tests, including vehicle-based trajectory evaluation and unmanned surface vehicle (USV) testing.

Test results and evaluation activities include:

• Good Satellite C/N₀: Monitoring of GNSS satellite signal quality
• Continuous RTK Correction Data Reception: Verification of RTK correction data reception during testing
• Trajectory Comparison: PolyExplore vs. Competitor: Visual comparison of navigation trajectories
• Land and Water Applications: Testing and evaluation for vehicle navigation and unmanned surface vehicle platforms

These results provide practical reference information for evaluating navigation performance. Actual performance depends on installation, GNSS conditions, correction availability, and the operating environment.

Typical Applications

• Autonomous Driving & ADAS
• Low-Speed Unmanned Vehicles & Smart Logistics
• Robotics & Autonomous Mobile Robots (AMRs)
• Mobile Mapping & Geospatial Data Collection
