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 Avionics’ Air Data Attitude and
Heading Reference System (ADAHRS). Additionally, in some installations the magnetic heading
is provided by the SV-MAG-236 remote magnetometer. When it is installed, it deactivates and
replaces the magnetic sensors in the ADAHRS.
Table 1 describes which inputs and sensors are used within the ADAHRS module to generate
the different displayed instruments.
