New series of GX3 Inertial Measurement Systems is launched

MicroStrain have released the third in their new series of GX3 Inertial Measurement Systems. The 3DM-GX3-45 high-performance, miniature system combines MEMS inertial sensors, a highly-sensitive GPS receiver, and a complex Extended Kalman Filter to generate optimal position, velocity, and attitude (PVA) estimates.

This combination of technologies creates better short-term GPS-out performance, sustained-G attitude performance, and provides higher rate PVA data than typical GPS and AHRS Sensors. Raw GPS data, IMU data, and filtered INS data are time-aligned and available as custom, user-defined packets (either by polling or continuous stream).

The 3DM-GX3-45 offers a range of navigation-related output quantities, including: estimated position, velocity, and attitude; position, velocity, and attitude uncertainties; bias- compensated angular rate, linear acceleration, local gravity magnitude and vector, and local magnetic field declination. Fully-calibrated inertial quantities include: total acceleration, angular rate, magnetic field, delta theta and delta velocity.

The ease and flexibility of managing these different data quantities at different sampling rates is made possible by the powerful Microstrain Inertial Packet Protocol (MIP). The 3DM-GX3-45 has a dual communication interface, which supports USB and RS-232. Starter kits include choice of USB or RS-232 interface cables. Applications include marine, automotive, communications, camera pointing, platform stabilisation and robotics.
