AHRS

The following AHRS sensors can be connected to the Enigma/Voyager/Odyssey/XTreme. They are connected to the Airtalk input in the rear of the EFIS display. If both sensors are used, you simply tie the signal lines from each sender together and connect to EFIS.

Made by MGL Avionics, these are some of the smallest aviation AHRS sensors available today.

SP-7 Attitude Sensor

What is it?
The SP-6 is a magnetic compass sensor (magnetometer) for use with all MGL Avionics products that show heading. It contains a three axis magnetic field sensor and a 3 axis accelerometer. The system used a Cortex M3 32 bit processor. If a SP-7 AHRS is used on the same communications link, tilt compensation can be performed using gyro based attitude data.

What is it?
The SP-7 AHRS is MGL Avionics's seventh generation AHRS system (attitude sensor) for use with all MGL Avionics products that display attitude. The core building blocks of the system includes a three axis ST MEMS rate gyroscope, a three axis ST MEMS accelerometer and an ARM Cortex 32-bit microprocessor system. The SP-7 will allow the display of attitude (horizon), G-force, turn rate, and slip/skid on MGL Avionics products that allow these features.

Advanced ARS

The SP-5 is our latest and greatest attitude sensor (the SP-6 is still required for compass). The SP-5 uses the same gyros used in several certified attitude sensors.

SP-5 Advanced Attitude SensorWhat is it?
The SP-5 contains 3 Silicon Sensing MEMS gyros (the same gyros used in certified AHRS units) and 3 Analog Devices MEMS accelerometers. Using a 16 bit data acquisition subsystem, a powerful ARM7 32 bit processor is used to provide stabilized attitude information. Together with an SP-2 magnetometer on the same Airtalk communications link, the gyro heading can be automatically slaved to the magnetic heading.
