Attitude & Heading Reference System


The LandMark™20 AHRS features very low noise gyros and accelerometers with excellent in-run bias as well as over temperature bias performance with ruggedized environmentally sealed packaging enclosure and a MILSPEC connector.


The unit is form, fit and function interchangeable with both the LMRK10 & 40 AHRS. The unit is ideal for applications demanding excellent performance coupled with challenging environmental requirements at low cost.


The signature feature of this AHRS 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 an attitude indicator display. This is combined with an accurate magnetometer for heading, that is calibrated over temperature, as well as pitch and roll angle outputs.





  • 9 Degrees of Freedom MEMS AHRS


This AHRS performance is optimized with fully compensated bias, scale factor, misalignment, g-sensitivity, heading, pitch and roll angles and altitude information. This is in a ruggedized environmentally sealed package that is EMI resistant and includes a MILSPEC connector.


The unit is highly durable and can withstand environmental vibration, shock and EMI typically associated with commercial aircraft requirements. The LandMark™ AHRS is well suited for commercial flight control, navigation, marine, antenna stabilization and pointing, general aviation as well as laboratory use.
