AMSAT is a name for amateur radio satellite organizations worldwide, but in particular the Radio Amateur Satellite Corporation (AMSAT) with headquarters at Washington, D.C. AMSAT organizations design, build, arrange launches for, and then operate (command) satellites carrying amateur radio payloads, including the OSCAR series of satellites. Other informally affiliated national organizations exist, such as AMSAT Germany (AMSAT-DL) and AMSAT Japan (JAMSAT).
UoSAT-2, which is also known as UO-11 and OSCAR-11, is a British satellite orbiting in Low Earth Orbit. The satellite functions as an amateur radio transmitter and was built at the University of Surrey. It launched into orbit in March 1984 and remains orbital and active, though unstable with irregular periods of transmission. All of the Analog telemetry channels have failed, making telemetry from OSCAR 11 useless. The satellite was still heard transmitting telemetry in 2015, thirty years after launch.
HAMSAT also known as HAMSAT INDIA, VU2SAT and VO-52 is a microsatellite weighing 42.5 kilograms (93.7 lb), providing amateur radio satellite communications services for Indian and international amateur radio operators. This satellite carries the in-orbit designation of VO-52, and is an OSCAR series satellite.
KiwiSAT, an amateur radio satellite developed by AMSAT-ZL, is to be New Zealand's first satellite. It is being designed and built by New Zealand radio amateurs supported by Massey University (Auckland) and various corporate sponsors.
SumbandilaSat, was a South African micro Earth observation satellite, launched on 17 September 2009 on a Soyuz-2 launch vehicle from the Baikonur Cosmodrome. The first part of the name, Sumbandila, is from the Venda language and means "lead the way".
UoSAT-1, also known as UoSAT-OSCAR 9 (UO-9), was a British amateur radio satellite which orbited Earth. 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 by six years, having received signals on 13 October 1989, before re-entering the atmosphere.
AMSAT-OSCAR 7, or AO-7, is the second Phase 2 amateur radio satellite constructed by the Radio Amateur Satellite Corporation or AMSAT. It was launched into Low Earth Orbit on November 15, 1974 and remained operational until a battery failure in 1981. After 21 years of apparent silence, the satellite was heard again on June 21, 2002 – 27 years after launch. At that time the public learned that the satellite had remained intermittently functional and was used surreptitiously for communication by the anticommunist opposition Fighting Solidarity during martial law in Poland.
Delfi-C3 is a CubeSat satellite constructed by students at the Delft University of Technology in the Netherlands. It is a 3-unit CubeSat, and was launched at 03:53:42 on 28 April 2008, as part of the NLS-4 mission, aboard a PSLV rocket, from the Second Launch Pad at the Satish Dhawan Space Centre in India. The launch was contracted by ISRO, through Antrix Corporation and UTIAS.
AMSAT-OSCAR 16, also known as AO-16 and PACSAT, is the in-orbit name designation of an amateur radio satellite of the OSCAR series. It was built by AMSAT and was launched on 22 January 1990 from Kourou, French Guiana on an Ariane 4 launch vehicle. It is in sun synchronous low Earth orbit.
Science policy in Malaysia is regulated by the Ministry of Science, Technology, and Innovation. The ministry focuses on five areas: biotechnology, ICT policy, industry, sea to space and core science and technology. Other ministries, such as the Ministry of Agriculture and the Ministry of Health also have science departments. Training in scientific areas was promoted during the 1970s and 1980s. From 1987 to 1997 research and development used 0.24% of GNP, and in 1998 high-tech exports made up 54% of Malaysia's manufactured exports.
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.
OSCAR IV was the fourth amateur radio satellite launched by Project OSCAR and the first targeted for Geostationary orbit on 12 December 1965. The satellite was launched piggyback with three United States Air Force satellites on a Titan IIIC launch vehicle. Due to a booster failure, OSCAR 4 was placed in an unplanned and largely unusable Geostationary transfer orbit.
LituanicaSAT-1 was one of the first two Lithuanian satellites. It was launched along with the second Cygnus spacecraft and 28 Flock-1 CubeSats aboard an Antares 120 carrier rocket flying from Pad 0B at the Mid-Atlantic Regional Spaceport on Wallops Island to the International Space Station. The launch was scheduled to occur in December 2013, but later was rescheduled to 9 January 2014 and occurred then. The satellite was broadcasting greetings of Lithuanian president, Mrs. Dalia Grybauskaitė. The satellite was deployed from the International Space Station via the NanoRacks CubeSat Deployer on February 28, 2014. All LituanicaSAT-1 subsystems have been turned on, tested and proved to be working properly. The mission is considered a complete success by its team of engineers. The mission ended upon the reentry and disintegration of the satellite on July 28, 2014.
FUNcube-1 is a complete educational single unit CubeSat satellite with the goal of enthusing and educating young people about radio, space, physics and electronics. It is part of a program which aims to launch more of these educational CubeSats. It is the first satellite with outreach as its primary mission.
Es'hail 2 is a Qatari satellite, launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. Es'hail 2 was built by Japan's Mitsubishi Electric company, and operates at 26° East longitude along a geostationary orbit to provide direct-to-home television services in the Middle East and North Africa region. The satellite features 24 Ku-band and 11 Ka-band transponders to provide direct broadcasting services for television, government and commercial content distribution. In addition to commercial services, the payload of Es'hail 2 includes a linear transponder with a bandwidth of 500 kHz and 8 MHz for the amateur radio satellite service, with uplink on 2.4 GHz and downlink on 10.45 GHz.
EcAMSat, or E. coli AntiMicrobial Satellite, was NASA's first 6U CubeSat, developed to investigate the effects of microgravity on the antibiotic resistance of E. coli. The spacecraft was launched aboard an Orbital ATK Antares rocket from Wallops Flight Facility on 12 November 2017, and was deployed from the International Space Station on 20 November 2017.
Fox-1D, AO-92 or AMSAT OSCAR 92 is an American amateur radio satellite. Fox-1D is a 1U CubeSat developed and built by AMSAT-NA. Fox-1D carries a single-channel transponder for mode U/V in FM. Fox-1D has an L-band converter, which allows the FM transponder to be switched on an uplink in the 23 centimetres (9.1 in) band.
Fox-1B, AO-91 or AMSAT OSCAR 91 is a United States amateur radio satellite. It is a 1U Cubesat, was built by the AMSAT-NA and carries a single-channel transponder for FM radio. The satellite has a whip antenna for the 70 cm and 23 cm bands (uplink), and a second antenna for the 2 m band (downlink). Fox-1B is the second amateur radio satellite of the Fox series of AMSAT North America.
UiTMSAT-1 was a Malaysian nanosatellite, built primarily by Universiti Teknologi MARA (UiTM) as part of the multi-nation Birds-2 project. The 1U CubeSat was launched into space on 29 June 2018 and deployed from the International Space Station (ISS) on 10 August 2018.
