Outernet is active for some years now and attempts to realize specific goals :

Afbeeldingsresultaat voor outernet wiki

To provide information without censorship for educational, emergency purposes,
‘news, civil information, commodity prices, weather, construction plans for open source
farm machinery’, and other types of information.
Providing access to ‘courseware’, which includes textbooks, videos, and software.

Basically Outernet is a ‘broadcast datastream’ via the geostationary L-band Inmarsat infrastructure,
using very little bandwidth resulting in around 2.1 kbit/s downstream, and having global coverage.

From what I understood Outernet initially broadcasted from Ku-band satellites (like HotBird)
but changed to L-band. With this change a whole new community emerged, building L-band (1542 MHz)
antennas and receivers dominantly based on cheap RTL-SDR dongles.

Although the Outernet philosophy attempts to present itself as low level and
‘open’ as possible, the core files to decode the transmitted data are proprietary (to some extend)
and/or not public domain.

The latter urged Daniel Estévez EA4GPZ to reverse engineer the Outernet protocol.
Last year he gave a lecture at 33C3 in Germany on this topic (click here to watch his presentation).

Somewhat later/almost simultaneously Pascal Brisset F4DAV ‘hacked’ the Outernet protocol
(with assistance from the information provided by EA4GPZ ?) from a DVB-S perspective.

Having read a lot of information on the internet about Outernet today, Outernet advocates a
nice mission but I doubt it’ll have an added value, besides being a nice and nerdy technical project.

An illustrating posting can be read here.

Considering the latter, a nice technical project with ‘no use’, it is still fun to play with it, so I did.

The HAM-radio community seduced the Outernet CEO to forward APRS packets.

It took me some fiddling to understand how to route APRS-packets to Outernet but after
half an hour I read my first transmission relayed by Outernet!

Below a screenshot as proof (being the first Dutch HAM to have Outernet relayed APRS-packets ? ) !
(and yes, there is a wireless component involved, a 5.6 GHz HAMnet link !)
