VN-200
Miniature industrial-grade GNSS/INS with a 72-channel L1 receiver and Kalman filtering for position, velocity, attitude and heave at up to 400 Hz.
Description
The VN-200 is a miniature GNSS-aided inertial navigation system (GNSS/INS). It combines 3-axis gyros, accelerometers and magnetometers, a barometer and a 72-channel L1 GNSS receiver, and uses Kalman filtering to estimate position, velocity and attitude. Introduced in 2012, it was the world's first GNSS/INS in a single surface-mount package.
Key features
- SMD version (24 x 22 x 3 mm) runs from a single 3.2-5.5 V supply
- Rugged anodized-aluminum version with a locking 10-pin connector and MMCX antenna connector
- 0.2° (1σ) INS heading, 0.03° pitch/roll, 1.0 m RMS horizontal position, < 0.05 m/s velocity
- Heave accuracy of 5% or 5 cm
- Made in the USA, ITAR-free
Applications
VectorNav's marine page lists the VN-200 for surface vessel navigation, including unmanned surface vehicles, high-speed craft and stabilized marine systems.
