It was built at the University of Surrey and launched into low Earth orbit on 6 October 1981. It exceeded its anticipated two-year orbital lifespan[1] by six years, having received signals on 13 October 1989,[1] before re-entering the atmosphere. This was the first of several UoSAT satellites; followed by UoSAT-2. MissionLike its successor UoSAT-2 it carried a CCD camera and a Digitalker speech synthesiser,[2] and transmitted telemetry data on a 145.826 MHz beacon at 1200 baud using asynchronous AFSK.[3] The Astrid package sold by British firm MM Microwave,[4] consisting of a fixed frequency VHF receiver set and software for the BBC Micro, could display the telemetry frames from either UoSAT-1 or UoSAT-2.[2] UoSAT-1's solar arrays were of an experimental design reused for UoSAT-2.[2] Computers and Data ProcessingThe primary computer for the satellite was the RCA 1802 microprocessor.[5] A secondary microprocessor was also employed, the "F100L" (a Ferranti 16-bit processor). Memory was 16K of DRAM.{{-}} References{{Portal|Spaceflight}}1. ^{{Cite web|last=Bopp|first=Matthias|title=Homepage DD1US / Sounds from Space|url=http://www.dd1us.de/spacesounds%202.html|date=2 October 2010 |accessdate=13 October 2010}} {{UoSAT}}{{Orbital launches in 1981}}{{DEFAULTSORT:Uosat-Oscar 9}}{{Amateur-radio-stub}}{{UK-spacecraft-stub}}2. ^1 2 3 {{cite journal |last = Cook |first = Mike |date= June 1986 |title = Way into the world of satellite telemetry: Mike Cook reviews the Astrid telemetry package |journal = The Micro User |volume = 4 |issue = 4 |pages = 100–1 |publisher = Database Publications |location = Stockport, UK |issn = 0265-4040}} 3. ^{{cite web |url=http://www.amsat.org/amsat-new/satellites/sat_summary/uo11.php |title=Amateur Satellite Summary - UoSAT-OSCAR-11 |author= |website=AMSAT |publisher=AMSAT |accessdate=17 January 2014}} 4. ^{{cite web|url=http://www.g3tpw.co.uk/Page8EvenMoreFAQs.html|title=Even More FAQs|last=Webb|first=Stephen R.|date=16 January 2008 |accessdate=13 October 2010|deadurl=yes|archiveurl=https://web.archive.org/web/20090802162736/http://www.g3tpw.co.uk/Page8EvenMoreFAQs.html|archivedate=2 August 2009|df=}} 5. ^{{Cite web|url=http://www.retrotechnology.com/memship/amsat.html|title=The COSMAC 1802 and AMSATs, OSCARs and UoSATs|last=|first=|date=|website=|publisher=|access-date=}} 4 : University of Surrey|Amateur radio satellites|Satellites of the United Kingdom|Spacecraft launched in 1981 |
