The LandMark^TM 20 AHRS eXT is ideal for applications demanding excellent performance coupled with challenging environmental requirements at low cost. In addition to low noise gyros and accelerometers the unit features ultra low power consumption, small size, light weight, long life MTBF and enhanced packaging with improved environmental-sealing and EMI protection. The signature feature of the LandMark^TM 20 AHRS eXT is the low noise gyros and accelerometers, which enable precision measurement and improved in-run and bias over temperature as well as reduced jitter on the attitude indicator display. The AHRS's performance is optimized with fully temperature compensated bias and scale factor and compensated misalignment and g-sensitivity.
