GN-200A datasheet
Galaxy Navigation Corp.
GN-200A INS/GPS/AHRS
The GN-200A is an excellent, small size and low weight, silicon MEMS
based Inertial Measurement Unit (IMU) with integrated barometer,
high precision digital compass and next-generation technology GPS
for control and navigation applications. It provides a wide range of
output modes and advanced settings for specific usage scenarios.
GN-200A has an embedded Attitude and Heading Reference System (AHRS) and
navigation computer which runs a real-time Kalman filter providing drift-free and 3-D
orientation data. This navigation system can provide directional and positioning
information of 3D acceleration, three-axis angular rate, roll & pitch, and heading, etc. It
can be widely applied in ground, marine as well as aviation area to provide powerful
synergistic Guidance, Navigation & Control (GN&C).
