Attitude/Heading Reference System (AHRS)
AHRS

Available functions in  this category depend on the capabilities of the sensor package connected. The  following list shows functions available with the SP-6 compass sensor and SP-7 attitude sensor.

SP-6 Magnetometer (Compass sensor)
SP-6 Magnetometer Compass sensor

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.

    Size:     Approx 3.5” x 3.5”
    Weight: 175g with connector (6 oz)
    Power consumption: 50mA / 120mA (heater on)

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.
