I've recently become interested in python and, as an exercise, I thought
I might attempt to port my C++ predict client to python. The problem is
that I haven't advanced far enough yet to know how to use python sockets.
I'd like to know how to connect to the predict server. Can anyone point
me
There is so much variability in the footprint that #1 or #2 would probably
suffice. Working satellites on the fringes of AOS and LOS wheigh heavily on
your location, surroundings, and equipments that it's impractical, it's
just a visual "references" that shows relative satellite reception.

Don't think you can get Robert NH7WN he needs 13 deg. Elevation to get this
way.
You could email Tom K4XV on Kauai, he is getting is station together and
also has access to the Kauai College Station.
His email is good on qrz.com.

Further to what Gus writes, I think Method #3 will suffer from two
assumptions, giving an impression of precision when less should be
expected. First, you are highlighting the shadows that mountains and
other terrain should give, but which are only applicable to visible
light. Radio waves bend
I'd like to try some very limited satellite operation from my mobile,
using an FT-857D. I know this rig is not ideal for satellite ops,
because it lacks full duplex
capability. But it is all mode, and should allow me to operate several
different satellites using portable antennas from the truck.
Does anyone know a way around the problem that gpredict can only control the
FT-817 downlink frequency. I suspect there is a limitation in the hamlib
control for this rig. The gpredict manual says 'the TX frequency can not be
adjusted via the CAT interface (e.g. Yaesu FT-817)' but SatPC32 on w
My humble suggestion:
1. Implement option 1 for the satellite footprint.
2. If you decide to give the users the ability to input their location, them
the option to provide either a single minimum elevation angle or a local map --
i.e., 360 individual minimum elevations as a function of Azimuth

InstantTrack uses a spherical Earth model for ground footprints.

Any Hawaii hams around for FO-29 pass today (3-25) 19:30utc to Iowa EN31

I would suggest you go with #1 or #2. The added complexity of method #3
probably won't pay any significant dividends in practical terms. You
could always implement #3 for version II. :-)
Will you be considering squint? Frankly, I'm not sure any current

I can not decide how to implement ground footprints with my google earth
satellite tracker. I figured, since I can't make up my mind, I should get a
second (and third, and fourth) opinion. For this thread, I would like to
discuss how satellite ground-footprints should be implemented. A quick
