Amateurfunksatelliten sind Satelliten oder Raumsonden, die meist von Funkamateuren gebaut oder betrieben werden und die zur Kommunikation die Amateurfunkbänder benutzen. Manche dieser Satelliten enthalten Transponder, die als Relaisstationen für verschiedene Betriebsarten genutzt werden können. Andere enthalten Experimente oder Kameras, deren Daten zur Erde übertragen werden. Einige Amateurfunksatelliten mit einer Erdumlaufbahn werden als OSCAR (Orbiting Satellite Carrying Amateur Radio) bezeichnet. (de)
An amateur radio satellite is an artificial satellite built and used by amateur radio operators. It forms part of the Amateur-satellite service. These satellites use amateur radio frequency allocations to facilitate communication between amateur radio stations. Many amateur satellites receive an OSCAR designation, which is an acronym for Orbiting Satellite Carrying Amateur Radio. The designation is assigned by AMSAT, an organization which promotes the development and launch of amateur radio satellites. Because of the prevalence of this designation, amateur radio satellites are often referred to as OSCARs. These satellites can be used free of charge by licensed amateur radio operators for voice (FM, SSB) and data (AX.25, packet radio, APRS) communications. Currently, over 18 fully operational amateur radio satellites are in orbit. They may be designed to act as repeaters, as linear transponders, and as store and forward digital relays. Amateur radio satellites have helped advance the science of satellite communications. Contributions include the launch of the first satellite voice transponder (OSCAR 3) and the development of highly advanced digital "store-and-forward" messaging transponder techniques. The Amateur Radio Satellite community is very active in building satellites and in finding launch opportunities. Lists of functioning satellites need updating regularly, as new satellites are launched and older ones fail. Current information is published by AMSAT. AMSAT has not been actively involved in the launch and operation of most amateur satellites in the last two decades beyond allocating an OSCAR number. (en)
Satelit radio amatir adalah satelit buatan yang dibangun dan digunakan oleh operator radio amatir untuk digunakan dalam layanan satelit radio amatir. Satelit radio amatir pertama adalah OSCAR-1, diluncurkan pada tanggal 12 Desember 1961, di Amerika Serikat. Program selain OSCAR telah disertakan Iskra (Uni Soviet) sekitar tahun 1982, JAS-1 (Fuji-OSCAR 12) (Jepang) pada tahun 1986, RS (Uni Soviet dan Rusia), dan CubeSats Satelit amatir pertama berisi beacon telemetri. Sejak 1965, sebagian besar satelit membawa transponder linier untuk komunikasi dua arah secara real time. Beberapa satelit memiliki papan buletin untuk komunikasi digital-store-and-forward, atau digipeater untuk koneksi radio paket langsung. Satelit amatir telah diluncurkan ke orbit Bumi rendah dan ke orbit yang sangat elips. (in)
