Data Sheet Miniature Attitude Heading Reference System with GPS The 3DM-GX36 -35 high-performance, miniature Attitude Heading Reference System (AHRS) with GPS, combines MEMS sensor technology and a highly sensitive embedded GPS receiver. It incorporates a triaxial accelerometer, triaxial gyro, triaxial magnetometer, temperature sensors, and an on-board processor running a sophisticated fusion algorithm to provide orientation, inertial, and GPS measurements. Data from the GPS receiver is time synchronized with the inertial sensors and all inertial and GPS data are available as user-defined packets (either by polling or continuous stream). The 3DM-GX38 -35 provides a perfect platform for users to develop their own navigation solutions. Features & Benefits Product Overview smallest and lightest AHRS with GPS available on the market fully temperature compensated over operational range calibrated for sensor misalignment, gyro g-sensitivity, and gyro scale factor non-linearity to third order improved performance under vibration, as inertial sensors are sampled at 30 kHz and digitally filtered and scaled into physical units; coning and sculling integrals are computed at 1 kHz MIP protocol provides fully customizable data output: inertial data up to 1000 Hz and GPS data up to 4 Hz with individual data quantity AHRS output includes Euler angles, rotation matrix, deltaTheta, de Ita Velocity, quaternion, acceleration, angular rate and magnetic NMEA GPS protocol records and UBX GPS protocol records available provides time synchronized inertial and GPS data enabling users to develop navigation solutions versions available from 1.7 g to 50 g and 507s to 12007s rugged aluminum enclosure with precision alignment holes ROHS compliant The 3DM-GX38 -35 offers a range of fully calibrated inertial measurements including acceleration, angular rate, magnetic field, deltaTheta and deltaVelocity vectors, Euler angles (pitch, roll, and heading), rotation matrix and quaternion. Its GPS data quantities include LLH position, NED velocity, ECEF position and velocity, DOP data, UTC time, GPS time, clock info, GPS fix, and SVI. All quantities are fully temperature compensated and are mathematically aligned to an orthogonal coordinate system. The angular rate quantities are further corrected for g-sensitivity and scale factor non-linearity to third order. The 3DM-GX38 -35 architecture has been carefully designed to substantially eliminate common sources of error such as hysteresis induced by temperature changes and sensitivity to supply voltage variations. Gyro drift is eliminated in AHRS mode by referencing magnetic North and Earth's gravity and compensating for gyro bias. On-board coning and sculling compensation allows for use of lower data output rates while maintaining performance of a fast internal sampling rate. For those users, integrators or OEMs who develop their own orientation and navigation applications, the 3DM-GX38 -35 is shipped with a complete Data Communications Protocol guide that provides access to the powerful MicroStrain Inertial Packet Protocol (MIP). Applications of your own design can readily be developed in any coding language and on any computing platform including microprocessors. The 3DM-GX38 -35 is initially sold as a starter kit consisting of an AHRS+GPS module, RS-232 or USB communication and power cable, software CD, user manual and quick start guide. host based inertial aided GPS navigation location tracking of vehicles or personnel unmanned vehicle navigation platform stabilization, artificial horizon antenna, satellite and camera pointing biomechanics, biomedical animation automotive, marine, military heavy equipment, container handling virtual reality, computer science reconnaissance, surveillance and target acquisition system triaxial gyros triaxial mags triaxial accels sensor signal calibration data user settable MicroStrain* Little Sensors, Big Ideas.
