Site Information

Folks,

On my ADS-B Site Information it shows the following;

Antenna elevation above ground: 3.6576 meters
Ground elevation: 73 meters

I don’t know exact figures but indoor aerial in upstairs room so I’ve merely estimated it to be around 12 feet above ground level.

What does ground elevation refer to?

Thank you for quick reply.

It’s also worth mentioning that the antenna elevation doesn’t matter too much so long as it is approximately correct (say, within 100m)

That’s a good thing because the map shows my house lot elevation at 19m AMSL when, in fact, it is 3m AMSL.

You can directly set the AMSL value if you know it.

Will do.

FA calculates my elevation at 1m AMSL.
