Send it via outer space

Some thoughts and ideas on satellite transmission

How can I send via Satellite

During the workshop Satellite/Boarder/Footprint at HMKV the question cam up if it is possible to send directly to a satellite. During the Workshop several was of receiving satellites came up. A lot of art projects receive satellite data shown during the workshop and stored in the allready existing Artist Working With Satellites List by Max Neupert. Lisa Parks showed satellite TV enthusiasts covering their whole house with sat dishes to receive a broad range of signals. She showed as well improvised, handcrafted dishes made of metal pots. So there are ways to receive. But is it possible to send information directly via satellite in the context of an artistic project? Of course it is but it depends on the budget. So what can one do? Collect information and calculate.....

Transmitting/Receiving

Sharing information via electro magnetic fields is a highly protected form of communication. A small Number of frequencies can be received for several applications in everyday life e.g Radio(UHF), TV(UHF/Satellite), Internet 2.4 Ghz. surveillance cameras 2.4 Ghz, GPS,... Its allowed to send in some of those frequencies, like in the 2.4 Ghz frequency used for WiFi internet and other civil transmission.. Most other Frequencies are forbidden for public use. Radio Amateurs or Ham Radio Amateurs have the right to use some after passing a quite complex test on technology and laws of radio communication. Unlike the untested public radio user Ham Radio Amateurs are allowed to send on the frequencies they are receiving. The Ham Radio community is a world wide network based on privat equipment reaching from very low level to highly advanced technology. Most of the Radio Amateurs search for signals comig from a far out place. The aim of transmission is as well to reach a far away receiver. If another amateur is found both exchange their radio amateur name via voice, talk a bit and log the contact. Most of Ham Radio Amateurs send postcards after a contact. Those postcards are in a special For special events Radio Amateurs search in cars wih mobile systems for hidden transmitters. The Ham Radio communication structure is supported by several states in form of special activities e.g. satellite launches cause Radio Amateurs could act as a back up communication network in case of emergency or war. EXAMPLE??? The launched Satellits are builded by private initiatives. Thehistory of home made Satellite goes back to 1960 when a team of 6 Radio Amateurs builded a fully functional Satellite named OSCAR 1 [ http://projectoscar.wordpress.com/project-oscar-history/ ]. The Satellite was launched in Space from WHERE??? and WHO LAUNCHED IT??? It was sending a coded hi from outer space to other Ham Radio Enthusiast [ http://projectoscar.wordpress.com/project-oscar-history/oscar-i-newspaper-article/ ]. Nowadays the small group developed into the international AMSAT community for amateur satellites. A Description of the .... amateur satellites and there frequencies as well as an explanation of the transmission process and the equipment is displayed online by the AMSAT organisation [ http://www.amsat.org/amsat/intro/sats_faq.html#RTFToC19 ].

Satellite communication

Beside secret and known satellites launched by states like China, USA, Japan, Russia, Germany, France, etc... for militarian and secret service use there are numberous satellites for private use. Those satellites stream live TV casts, normal TV shows, send SMS or Email and transfer data or voice through outer space to the earth. The owners of all existing satelllites are shown here:...............

Becoming a Ham Radio Amateur

Becoming a Ham Radio Amateur is quite a hard work but not very complicated. If you learned your lessons from a book, a CD-Rom [ http://www.vth.de/shop/funk.html?tx_ptgsacategories_pi1[filter]=85&tx_ptgsacategories_pi1[filter-1]=4 ] or online [ http://www.dj4uf.de/lehrg/index.html ] you can pass the test at your national agency, that is in charge for radio frequencies. In Germany this is Bundesnetzagentur [1]. The dates for the test in different cities around germany are displayed here: [ http://www.afup.a36.de/aktuell/termine.html ].
