Inertial Sensors for Measurement of Orientation, Inclination and AttitudeMicroStrain Inc.’s line of advanced inertial sensors provide a range of measurement options including orientation (pitch, roll, yaw or azimuth), single axis or dual axis inclination, linear acceleration, and angular rate. Microstrain offers simple inclinometers (or tiltmeters), inertial measurement units (IMUs), attitude heading reference systems (AHRS), and integrated GPS systems. Designed for applications from personel tracking and drone navigation to downhole exploration.

List of MicroStrain Inertial Sensors

  • 3DM-GX3-45 Miniature GPS-Aided Inertial Navigation 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.
  • 3DM-GX3-35 Miniature GPS-Aided Attitude Heading Reference System (AHRS) combines MEMS sensor technology and a highly sensitive embedded GPS receiver. It incorporates a triaxial accelerometer, triaxial gyroscope, triaxial magnetometer, temperature sensors, and a dedicated 32 bit processor running a sophisticated fusion algorithm to provide orientation, inertial, and GPS measurements.
  • 3DM-DH3 Downhole Orientation Sensor and Data Logger incorporates acceleration sensors, magnetic field sensors, and temperature sensors, together with an on-board microprocessor, embedded software algorithm, non-volatile memory for configuration, flash datalogging memory, and serial communication interface. 3DM-DH3 provides accurate drill path measurements including Inclination, Azimuth, GTF, MTF, Dip Angle, sensor temperatures, G-TOT and H-TOT.
  • 3DM Solid State 3-axis Pitch, Roll, and Yaw Sensors – Triaxial sets of accelerometers and magnetometers for pitch, roll and yaw measurement. Orthogonal arrays of magnetometers and accelerometers are used to compute the pitch, roll and yaw (also refered to as heading or azimuth) over a wide angular range.
  • FAS-A Inclinometer is an Accelerometer based Flexion Angle System that measures 360˚ of inclination on one axis or ±70˚ on two axes. It has Onboard user programmable infinite impulse response (IIR) digital filter. It has an option to measure 360° of inclination on one axis or ±70° on two axes.
