Gladiator launches MEMS attitude and heading reference system
The new ultra-low noise MEMS inertial suite with ARW Noise of 0.001°/sec/√Hz enables high accuracy pitch, roll and heading angles
Gladiator Technologies has released a new high performance MEMS product family, the LandMark 50 Attitude and Heading Reference System (AHRS).
This new AHRS builds upon the successful heritage of the company's LandMark AHRS product families, including the LandMark 10, 20, 30 and 40.
The LandMark 50 AHRS is form, fit and function interchangeable with the proven LandMark 30 AHRS, yet offers substantial improvement in performance utilizsng its newest high performance MEMS gyros and accelerometers.
All LandMark AHRS's use only gyros and accelerometers to accurately calculate pitch and roll angles. The unit includes a hard and soft iron calibrated temperature modelled triaxial magnetometer for heading as well as internal barometric pressure sensor.
The internal software will automatically provide turning error correction with an external customer supplied velocity input, either analogue or digital. All Gladiator AHRS's share a common messaging protocol for a 'common cockpit' approach enabling users the option to choose the AHRS performance, size, weight and price that best suits their application without having to rewrite any interface software.
The LandMark 50 AHRS features robust environmental sealing for EMI protection with an RS485 data rate of 100Hz (4 KHz internal sampling rate) and offers many advanced performance features as listed below.
Pitch & Roll Angles ±0.1° typical
Heading Angle ±0.5° typical
Wide Input Voltage Range +6V to +36V
Low Gyro Noise 0.001°/sec/√Hz (0.042°/√Hour)
