Re: [amsat-bb] Lock on Tracking

["Dave Johnson" <Dave.Johnson@xxxxxxxxxx>]

Hi Rod,

An active solution might be to do the the equivalent of what deep space
satellites do when they lose lock on the earth for some reason, they
'cone'.
In other words they set up a motion which subtends a cone of the
radiation
pattern of the antenna. At some point in the motion around the cone the
signal strength will increase and that will give an indicaton of the
direction. The satellite then manoeuvres 'the cone' in than direction,
and
reduces it's diameter and continues to do this repeatedly until a lock
is
found. A cone of zero angle.

A neat trick but I'm not sure that my 5500 would cope with all than
movement!
