NAV440CA

The Crossbow NAV440 is a combined GPS Navigation and GPS-Aided Attitude & Heading Reference system (AHRS) that utilizes both MEMS-based inertial sensors and GPS technology to provide an unmatched value in terms of both price and performance. Developed in response to over a decade of experience in a wide variety of airborne applications including thousands of deployed units and millions of operational hours.• Built-in GPS receiver for position and velocity measurement• GPS data synchronization clock• Configurable high-performance Extended Kalman Filter (EKF) algorithms tunable to a wide range of applications• Water resistant, vibration resistant, light-weight design• EMI protection for trouble-free operation• Continuous Built-in-Test The NAV440 provides consistent performance over a wide temperature range in challenging EMI environments across a broad range of input power conditions. It is designed and configu- rable for use in a number of different applications including unmanned vehicle control, land vehicle guidance, uncertified avionics, and platform stabilization.With GPS integration, the NAV440 system also provides GPS-Aided velocity data at up to 100 Hz. Velocity data derived from the inertial systems improves stability and reduces the latency associated with stand-alone GPS measurements.Each NAV440 system comes with a GPS antenna, Crossbow’s User’s Manual and NAV-VIEW 2.0 software to assist with system development, evaluation, and data acquisition. A High-Gain, Aircraft Quality GPS Antenna option is also available.
