Preferred term

NAV420 Navigation Data  

Definition

  • roll, pitch, and heading using MEMS technology in commercial, industrial and aerospace markets since 1998. The Crossbow Navigation System, or NAV420CA uses a 3-axis accelerometer and a 3-axis rate sensor to make a complete measurement of the dynamics of the system. The addition of a 3- axis magnetometer inside the NAv420CA allows it to make a true measurement of magnetic heading without an external flux valve. With the built-in GPS receiver, the combined system becomes a low-cost INS that can output location, velocity and acceleration. The Crossbow NAV420CA is a solid-state equivalent of a vertical gyro/artificial horizon display combined with a directional gyro, flux valve and Global Positioning System (GPS). (en)
