Starlink routing

The original and traditional high-cost way of how this is done for MEO/LEO
is exemplified by an o3b terminal, which has two active motorized tracking
antennas. The antenna presently in use for the satellite that is overhead
follows it until it's descending towards the horizon, while at the same
time the second antenna aims itself at where the next 'rising' satellite is
predicted to appear at the opposite horizon, and forms a link to it.
Make-before-break. If anyone has seen photographs in their marketing
material/videos of the Oneweb beta test earth stations in Alaska they are
operating using the same general concept.

Oneweb has clearly positioned their market focus for telecoms and ISPs and
large enterprise end users, because their CPE equipment is considerably
larger, expensive and more power hungry. The beta test sites I've seen
installed on top of a telecom equipment shelter occupy an area
approximately 8 feet long x 4 feet wide including radomes and mounting.
