System Overview
• GSU 25
Garmin Sensor Unit sub-system for the G3X Touch (Air Data Computer (ADC), and
–
the Attitude and Heading Reference System (AHRS))
– ADC: Processes data from the pitot-static system and outside air tem-
perature (OAT) sensor.
– AHRS: Provides aircraft attitude and heading information to the PFD.
The AHRS contains advanced sensors (including accelerometers and rate
sensors) and interfaces with the Magnetometer to obtain magnetic field
information, with the ADC to obtain air data, and with the GDU to obtain
GPS information. AHRS operation is discussed later in this section.
