DMU30
High Performance MEMS
HPIM
MU)
Inertial Measurement Unit (HPIMU)
Description
y
DMU30 is the first of a new family of High Performance
MEMS IMUs (HPIMU) incorporating precision VSG3QMAX
high-Q inductive resonating ring gyroscopes and
capacitive accelerometers.
im
Key features
in
ar
DMU30 is a six-degree-of-freedom inertial measurement
unit providing precise 3-axis outputs of angular rate and
acceleration, delta angle and velocity, and temperature,
at 200Hz.
Pr
el
• Precision 6-DOF MEMS Inertial Measurement Unit
• Silicon Sensing’s latest VSG3QMAX inductive gyro
and capacitive MEMS accelerometer
• Excellent Bias Instability and Random Walk
Angular - 0.2°/hr, 0.02°/hr Linear - 30μg, 0.05m/s/hr
• Non-ITAR
• Compact and lightweight - 68 x 61 x 62h (mm), 300g
• Internal power conditioning to accept 4.75V to 36V
input voltage
• RS422 interfaces
• -40°C to +85°C operating temperature range
• Sealed aluminium housing
• RoHS compliant
• In-house manufacture from MEMS fabrication to IMU
calibration
• Evaluation kit and integration resources available
• First class customer technical support
• Future developments and expansion capability,
e.g. magnetometer, barometer, GPS
DMU30 represents a realistic, alternative to established
FOG/RLG based IMUs due to its exceptional bias
stability and low noise characteristics, yet it is
comparatively compact, lightweight and offers low cost
of ownership.
Designed specifically to meet the growing demand from
high-end commercial and industrial market applications
for a ‘tactical’ grade non-ITAR IMU, DMU30 utilises
Silicon Sensing’s class leading MEMS inertial sensors
integrated and calibrated using an in-house state-ofthe-art test facility.
Applications
• Hydrographic surveying
• Airborne survey and mapping
• INS (Inertial Navigation Systems)
• AHRS (Attitude and Heading Reference System)
• GPS drop-out aiding
• Maritime guidance and control
• GNSS (Global Navigation Satellite System)
• Autonomous vehicle control and ROVs
• Machine control
• MEMS alternative to FOG/RLG IMUs
