Attitude & Heading Reference System


The LandMark™50 AHRS is one of the world's highest performance NON-ITAR MEMS AHRS's enabled by our G150Z gyros, which offers Open Loop FOG performance utilizing our own ultra-low noise MEMS gyros (0.0009°/sec√Hz) and accelerometers (0.02mg/√Hz). The AHRS features 1°/hr in-run bias stability, excellent bias and scale factor over temperature, rugged durability through both shock and vibration as well as precision alignment and modeled g-sensitivity.


Serial RS422/RS485 data at 1 kHz (4 kHz internally sampled) outputs fully compensated data for the most demanding applications.


Designed for stabilization, motion monitoring and navigation applications this IMU is ideal for commercial applications requiring high inertial performance approaching “FOG-Class”, yet available at much lower cost.


Other key advantages include low power consumption, small size, light weight and no inherent wear out modes for long life. An internal vibration isolation system enables temperature compensated RS422/485 output of delta velocity, delta theta, heading, pitch and roll angles and altitude information in a ruggedized package. Built-in software enables an external velocity input (user supplied) turning error correction as well as a 1pps sync.





  • 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.
