Description

VN-300 Rugged Dual Antenna GPS/INS is the world’s smallest INS with dual GPS antennas. Enabling accurate heading measurements without reliance on vehicle dynamics or magnetic sensors, the VN-300 provides unmatched performance under both static and dynamic operating conditions.

The VN-300 is a miniature, high-performance, dual GPS-Aided Inertial Navigation System that combines MEMS inertial sensors, two high-sensitivity GPS receivers, and advanced Kalman filtering algorithms to provide optimal estimates of position, velocity, and orientation for industrial applications. By utilizing two separate GPS receivers and antennas the VN-3oo enables accurate heading measurements without reliance on vehicle dynamics or magnetic sensors, providing unmatched performance under both static and dynamic conditions.

The VN-300 is ideal for applications that require a highly accurate inertial navigation solution under both static and dynamic operating conditions, especially in environments with unreliable magnetic heading and good GPS visibility.

 

VN-300 Rugged Dual Antenna GPS/INS Highlights:

  • Built-in Extended Kalman Filter running at 400 Hz with IMU outputs up to 800 Hz
  • Operates as a “True INS Filter” that does not force any requirements on alignment of the sensor to the velocity direction of a platform or specify the orientation of the sensor for initial alignment
  • Coupled position, velocity, & attitude estimates
  • Real-time gyro & accelerometer bias compensation
  • Raw pseudorange, Doppler, and carrier phase outputs
  • Dynamic accuracy better than 0.3° in heading, 0.1° in pitch & roll
  • Static accuracy better than 0.3° in heading, 0.5° in pitch & roll
  • Individually calibrated for bias, scale factor, misalignment, and temperature over full operating range (-40°C to 85°C)
  • Miniature self-locking MMCX connectors for GPS antennas
  • Coning & sculling integrals
  • User configurable messages using simple VectorNav binary protocol
  • Rugged aluminum package (10-pin Harwin connector)
  • Dimensions: 45 x 44 x 11 mm
  • Weight: < 30 grams
