VG440CA

The Crossbow VG440 is a MEMS-Based Vertical Gyro System that provides an unmatched value in terms of both price and performance. Developed in response to over a decade of extensive application expe- rience in a wide variety of airborne, marine, and land applications, the VG440 incorporates many new and enhanced design features including:• Configurable high-performance Extended Kalman Filter (EKF) algorithms tunable to a wide range of applications• Water resistant, vibration resistant, lightweight design• EMI protection for trouble-free operation• Continuous Built-in-Test• External GPS Input for Position/velocity aiding The VG440 operates as a standalone vertical gyro. Attitude performance can be enhanced by using the GPS Position/Velocity aiding input.Each VG440 system comes with a User’s Manual and Crossbow’s NAV-VIEW 2.0 software to assist users with system development, evaluation, and basic data acquisition.
