Software Compatibility
Moog Crossbow ’s 440 Series Inertial Systems are software compatible with any previous Moog Crossbow
products. The 440 Series units utilize a new extensible communication protocol which is documented in
. Additionally, the 440 Series includes numerous enhancements and features
that allow for better performance in many applications than the comparable 400 or 420 Series products.

440Series Inertial System Functions
This manual provides a comprehensive introduction to the use of Moog Crossbow ’s 440 Series Inertial System
functions listed in
below. This manual is intended to be used as a detailed technical reference and operating
guide for the 440 Series . Moog Crossbow ’s 440 Series units combine the latest in high‐performance commercial
EMS (Micro‐Electromechanical Systems) sensors and digital signal processing techniques to provide a small, cost‐
ffective alternative to existing IMU systems and mechanical gyros.

The 440 Series is Moog Crossbow ’s third generation of MEMS‐based Inertial Systems, building on over a decade of
field experience, and encompassing thousands of deployed units and millions of operational hours in a wide range of
land, marine, airborne, and instrumentation applications.
• At the core of the 440 Series is a rugged 6‐DOF (Degrees of Freedom) MEMS inertial sensor cluster that is
common across all members of the 440 Series . The 6‐DOF MEMS inertial sensor cluster includes three
axes of MEMS angular rate sensing and three axes of MEMS linear acceleration sensing. These sensors are
based on rugged, field proven silicon bulk micromachining technology. Each sensor within the cluster is
individually factory calibrated for temperature and non‐linearity effects during Moog Crossbow ’s
manufacturing and test process using automated thermal chambers and rate tables.
