VN-210 GNSS/INS

Overview

The VN-210 is a tactical-grade, high-performance GNSS-aided Inertial Navigation System (INS) designed for demanding applications. It integrates advanced 3-axis gyros, accelerometers, magnetometers, and a multi-band GNSS receiver (supporting L1/L2/E1/E5b bands), all powered by VectorNav’s proprietary Extended Kalman Filter (EKF) algorithms. This combination delivers precise, low-latency estimates of position, velocity, and attitude, even in challenging environments.

Key Features

• Dual-Band GNSS Receiver: The VN-210 features a multi-band GNSS receiver supporting L1, L2, E1, and E5b signals, enabling robust and accurate positioning across multiple satellite constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS).
• Industry-Leading INS Performance: VectorNav’s EKF INS algorithm ensures continuous, high-accuracy position, velocity, and attitude solutions, excelling under dynamic conditions.
• Flexible Packaging: Available in two options:
  • VN-210: Precision-milled, anodized aluminum enclosure for rugged applications.
  • VN-210E: Ultra-compact, board-mount version for SWaP-C (Size, Weight, Power, and Cost) constrained environments, weighing just 14 grams.
• Robust Positioning: Supports RTK, PPK, and SAASM/M-Code GPS for enhanced accuracy. Compatible with external GNSS receivers and IMUs for maximum flexibility.
• User Configurable Messaging: Offers both ASCII and VectorNav Binary message formats for seamless integration.
• Software Compatibility: Shares a common communication protocol with the entire VectorNav product line, simplifying system integration.
• True Inertial Navigation: No mounting orientation restrictions or configuration modes; automatic filter initialization and dynamic alignment for ease of use.
• ITAR-Free and Made in the USA: Ensures global availability with short lead times.
