[amsat-bb] Global Geo SATCOM system?

The O/S image for the Pi can be downloaded from:


... there is documentation at:


... but that doc currently seems to cover a lot more than the Pi and also a
lot more than just installing & using the system.

So, in summary it's a lot more straightforward than you would think from
the instructions:

-write the O/S image to a micro-SD card for the Pi

-point your antenna in the correct direction & plug it into the LNA > SDR >

-power on the Pi

-from a wi-fi capable computer, connect to SSID "Outernet"

-in a browser, connect to either or (mine uses the
former, but I noticed in the doc that they reference the latter)

-the browser interface will walk you through setting up an admin password;
you can explore the interface from there

Ref. the TP-Link dish, the feed is included.   I believe it's more-or-less
a dipole.
