Inertial and magnetic sensor products

This page contains information on MGL Avionics intertial and magnetic sensors to support various MGL Avionics instruments. These sensors are also available from a number of OEM users for use with their avionics.

If you are using any of these sensors together with avionics not made by MGL Avionics, please view documentation from your avionics manufacturer regarding operating and installation details. View the documents available from this page as supplementary only.

SP-6 magnetometer/electronic compass with advanced in-flight calibration algorithms for correction of hard and soft iron magnetic errors caused by ferro-magnetic materials in the aircraft. 

Using a newly developed, unique method the SP-6 is able to cancel out the effects of magnetically active parts and materials on board the aircraft without any form of external aiding. Very high levels of heading accuracy can be achieved even in very compromised mounting locations where the combined effects of field distortion levels exceed the strength of the Earth's own magnetic field.

The SP-6 dramatically simplifies electronic compass installation and elliminates the need for ground based compass swings and calibrations.

The new advanced algorithms have been introduced in production models from July15th 2013 onwards. Previous SP-6 models can be updated to the new firmware by the user or MGL representative using a freely available Windows based application.

SP-7 AHRS (Attitude and Heading reference system)

The SP-7 contains a three axis MEMS gyros and a MEMS 3 axis accelerometer.  A Cortex M3 32 bit processor is used to provide stabilized attitude information.
