3.4.5 Helios Avionics' SensorBox
A very good choice is to use the Helios Avionics' external SensorBox which provides not only independent attitude information (external AHRS) but also traffic and ILS data.
To reliably set up the SensorBox you need to make sure that you connect it to your tablet/smartphone via Wi-Fi-Direct. Then you can choose the 'Helios Avionics SensorBox'.
Other external boxes using the GDL90 protocol can also be used within 'Horizon'.
There are two Software Defined Radio receivers in our SensorBox. They can be used to receive ADS-B and ILS (Localizer and Glideslope) signals. In the future it may be possible to also receive other signals with the same hardware.
In the Radio Menu you can select which signals you want to receive (Wi-Fi connection to our SensorBox is required).
In case of ADS-B, the tuner is automatically set to 1090Mhz and no additional input is required. Other traffic which is received via ADS-B is indicated in the Synthetic Vision and in the Moving Map.
In case you want to use ILS you need to specify the localizer frequency. The corresponding glideslope frequency is automatically used via the Localizer/Glideslope frequency pairing.
The Localizer and Glideslope information is indicated in the Synthetic Vision.
Please note that there is a difference between the 1. Published runway heading; 2. Real runway heading; 3. Localizer approach course. For this reason an extrapolated approach via GNSS may differ from the Localizer course even if the threshold position is known perfectly. The difference is usually within a few degrees and less noticeable with a smaller distance from the threshold.
Also, with this SensorBox you can also receive ADS-B Traffic and Weather via 978 Mhz (USA).
