Lightweight Sensor

MicroStrain's 3DM-GX3 -35 is a miniature, lightweight sensor (23 g) with an attitude heading reference system (AHRS) and an onboard global positioning system (GPS) receiver. The AHRS and the GPS can independently provide time correlated measurements suited for applications where users are implementing their own host based GPS/INS Kalman Filter. The 3DM-GX3-35 is the newest member of the 3DM-GX3 family of sensors from MicroStrain. By migrating to the 3DM-GX3-35, users of the popular 3DM-GX3-25 AHRS can add GPS functionality while retaining a small footprint. The 3DM-GX3-35 is fully calibrated and temperature compensated throughout its operating range of -40 to +65C. Additionally, users are provided the option to specify sensor ranges including 5g, 1.7g, 16g or plus or minus 50g accelerometers, and 50/sec 300/sec, 600/sec and 1200 degree/sec angular rate sensors.

A new application programming interface (API) added features such as the ability to customize data messages for specific quantities at mixed data rates. This user control will allow for more accurate data, as well as eliminate extraneous information and data. An innovative new synchronized time stamping feature provides attitude and GPS data correlated in time for improved data analysis. The API is ready for the next generation of integrated inertial sensors, yet is also backward compatible allowing users to leverage existing code with minimal modification. This small integrated inertial/GPS unit is useful in a wide variety of applications including personnel tracking, platform stabilization, automotive and unmanned vehicles.
