Garmin GSU 25
ADAHRS For Garmin G3X System
The GSU 25 ADAHRS provides highly accurate and reliable referencing of the aircraft position, rate, vector and acceleration data, while providing the flexibility to be mounted in any of 16 different vertical or horizontal positions. Since the magnetometer is mounted external to the GSU 25, the unit may be mounted without worrying about the special installation needs of magnetometers. For enhanced system redundancy, G3X customers now have the option to install multiple ADAHRS units, or add one to their existing G3X installation.
When the GSU 25 is installed as a second ADAHRS, it may share the data from the magnetometer and outside air temperature probe already connected to the first GSU 73 or GSU 25 ADAHRS (via data on the CAN bus), or support is provided for optional installation of a redundant magnetometer and OAT probe if preferred.
The ADAHRS unit also supports new G3X features like optional Angle of Attack (AOA). The AOA system provides accurate, real-time measurement of wing performance to allow for both visual and audible stall margin indication to the pilot. The GAP 26 pitot/AOA probe is available in three versions: unheated, pilot-controllable heated or fully-regulated heated for protection against inflight icing.
