AOS EL

[Richard Kilmer]

Does anyone know what EL is used for AOS?  Is it 0.0 degrees or something above the horizon like 5 degrees.  Thanks.

Excellent question!

AOS occurs when the satellite crosses the 0 degrees elevation

[VK5HW]

AOS = Acquisition Of Signal

So if your horizon mask is 360 degree with 0 degree elevation then sure AOS = 0 . However, at my QTH I would need multipel AOS setting as I have 0 degree only into one small spot of the Compass. But even then I would most likely use 3-5 degree as the noise from ground sources would degrade SNR/CNR.

This might help, https://www.heywhatsthat.com/?view

Hi all,

tried to connect Skyroof to Pstrotator, but no success.

Has anyone successfully tried?
