MEMS Based IMU for Surveying and ADAHRS Applications
The iIMU-MM-04 is a MEMS based IMU consisting of MEMS gyros of class 10 deg/hr bias stability and 3 accelerometer axes of class 2 mg. Major features are:
- 0.15 deg/sqrt(hr) / 300 µg/sqrt(Hz); short time bias stability at const. temperature (AV) 0.5 °/hr, 0.1 mg.
- 1’000 Hz and 200 Hz data rate with
- power supply qualified to DO160E; FPGA Firmware and hardware according to DO254, DAL A.
- Used for Attitude Heading Reference, Surveying, Guidance & Control Applications
- iVRU-MM-04: the iIMU-MM-04 is available also with integrated strapdown / AHRS processor, additionally equipped with integrated L1 GPS engine, barometer and 3D magnetometer
- Also uncalibrated data available
- RS485 (UART) interface
- SYNC input for time stamping
The iIMU-MM-04 can be delivered with each 3 gyro and 3 acelerometer axes or in the AHRS version (iVRU-MM-04) in internal full redundant configuration (6 gyros, 6 accelerometers). The IMU is designed for ruggedized applications on land vehicles, naval vessels, helicopters and fixed wing aircrafts. The iIMU-MM-04 can be operated at an unregulated wide range power supply (10-34 V DC avccording to DO160E) and is protected against wrong polarity, HIRF, lightning and over-voltage up to 80 V. The data output is free running and the data are sent via RS485. Two redundant outputs and power inputs are available.
The iIMU-MM-04 is not subject of export restrictions (also not ITAR affected).
The iIMU-CFM-01 is interface compatible and baed on FOG technology.
