[sat] Hillbilly Tracking for Low Earth Orbit Satellites

[Jogi Hofmüller]

Folks,

Wieder mal ein lustiges Schnipsel aus dem aktuellen AMSAT-Newsletter :)

Hillbilly Tracking for Low Earth Orbit Satellites


In a video, Travis Goodspeed KK4VCZ describes his Low Earth Orbit
(LEO) satellite tracking system to the 30th Chaos Computer Congress
which took place December 27-30, 2013 at the Congress Center Hamburg
in Germany.

The YouTube description reads:

Satellites in Low Earth Orbit have tons of nifty signals, but they
move quickly though the sky and are difficult to track with fine
accuracy. This lecture describes a remotely operable satellite
tracking system that the author built from a Navy-surplus Inmarsat
dish in Southern Appalachia.

The entire system is controlled through a Postgres database, fed by
various daemons spread across multiple machines. So when I click on a
satellite on my laptop or cellphone, it runs “UPDATE target SET
name=’Voyager 1?;” and the motor daemon then begins to track the new
target while the prediction daemon maintains accurate estimates of
its position in the sky.

Additional daemons take spectral prints or software-defined radio
recordings of the targeted object for later review.

There is a description of the system on Travis Goodspeed’s Blog at
