terrain checkerboardAttitude/Heading Reference System (AHRS)
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 (horizon) sensor
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 information can be displayed on the EFIS?
Magnetic Heading
Wind speed and direction vector

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.
