SV-ADAHRS-20X
This guide uses SV-ADAHRS-20X to refer to both the SV-ADAHRS-200 and the SV-
ADAHRS-201. The SV-ADAHRS-200 and SV-ADAHRS-201 are identical in
performance and are designed to work together as a redundant ADAHRS solution.
An SV-ADAHRS-200 must be installed in your SkyView system in order to use an SV-
ADAHRS-201.
The primary flight instruments on your SkyView PFD are generated using a group of calibrated
sensors built into the SV-ADAHRS-20X ADAHRS module. All sensors are solid state–that is, there
are no moving parts. These sensors include accelerometers, which measure forces in all three
directions; rotational rate sensors, which sense rotation about all three axes; pressure
transducers for measuring air data; and magnetometers on all three axes for measuring
magnetic heading. These sensors form the core of Dynon’s Air Data Attitude and Heading
Reference System (ADAHRS).
Table 2 describes which inputs and sensors are used within the ADAHRS module to generate
the different displayed instruments.

Attitude Calculation
The SkyView artificial horizon display (attitude) is generated via a complex algorithm using a
multitude of sensors as described in Table 2. In normal operation SkyView uses airspeed to
