DAQAHRS GPS/INERTIAL SENSOR MODULE
A high performance Attitude and Heading Reference System (AHRS), Inertial Measurement
Unit (IMU) and Global Positioning System (GPS) providing position and inertial navigation
information with 10 degrees of freedom. DAQAHRS provides calibrated sensor data and a
drift free orientation solution using an Extended Kalman Filter. An ideal sensor module for
flight test instrumentation, recorder and system applications requiring position awareness.

The DAQAHRS GPS/Inertial Sensor Module integrates all the sensors needed to achieve full position
and motion sensing of any platform for data recording or position indication applications. The fused
data as well as the individual sensor data are available directly. Each interface can be configured to
output any parameter.
Full integrated with our DAQ9000 Data Acquisition System and other products in the DAQ range for
acquisition, recording and correlation with other data sources.
