VN-310 DUAL GNSS/INS

The VN-310 is a high-performance, tactical-grade Dual Antenna GNSS-Aided Inertial Navigation System. Leveraging advanced inertial sensor and GNSS technology, it integrates 3-axis accelerometers, gyros, magnetometers, and two multi-band L1/L2/E1/E5b GNSS receivers. This compact solution delivers precise position, velocity, and attitude data in both static and dynamic environments.

Packaging Options

• VN-310: Precision-milled, anodized aluminum enclosure.
• VN-310E: Ultra-compact, board-mount version for SWaP-C constrained applications.

Both models are certified to MIL-STD and DO-160G standards, making them ideal for demanding military and aerospace use. The VN-310E offers exceptional size and weight advantages without compromising tactical-grade performance.

Key Features

• True Inertial Navigation: No mounting orientation restrictions; automatic filter initialization and dynamic alignment.
• User Configurable Messaging: Supports ASCII and VectorNav Binary protocols.
• Seamless Integration: Shares a common communication protocol with the entire VectorNav product line.
• RTK/PPK Capable: Supports external RTCM 3 inputs and exportable RINEX data.
• Multi-Band GNSS: Integrated L1/L2/E1/E5b GNSS receiver.
• Rugged & Reliable: MIL-STD-810, MIL-STD-461G, DO-160G, and IP68 rated.
• ITAR-Free & Made in the USA: Fast lead times and global availability.

Performance Highlights
