Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. Data can include object Global Positioning System (GPS) coordinates, weather station telemetry, text messages, announcements, queries, and other telemetry. APRS data can be displayed on a map, which can show stations, objects, tracks of moving objects, weather stations, search and rescue data, and direction finding data.
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.
An amateur radio repeater is an electronic device that receives a weak or low-level amateur radio signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. Many repeaters are located on hilltops or on tall buildings as the higher location increases their coverage area, sometimes referred to as the radio horizon, or "footprint". Amateur radio repeaters are similar in concept to those used by public safety entities, businesses, government, military, and more. Amateur radio repeaters may even use commercially packaged repeater systems that have been adjusted to operate within amateur radio frequency bands, but more often amateur repeaters are assembled from receivers, transmitters, controllers, power supplies, antennas, and other components, from various sources.
The United States Naval Academy (USNA) Small Satellite Program (SSP) was founded in 1999 to actively pursue flight opportunities for miniature satellites designed, constructed, tested, and commanded or controlled by Midshipmen. The Naval Academy's aerospace laboratory facilities are some of the most advanced and extensive in the country. These facilities include structures labs, propulsion and rotor labs, simulation labs, wind tunnels with flow velocities ranging from subsonic to supersonic, computer labs, and the Satellite Ground Station. The SSP provides funds for component purchase and construction, travel in support of testing and integration, coordination with The US Department of Defense or National Aeronautics and Space Administration (NASA) laboratories or with universities for collaborative projects, and guides Midshipmen through the Department of Defense (DoD) Space Experiments Review Board (SERB) flight selection process.
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.
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.
TurkSat-3USat is a Turkish communications nanosatellite developed by the Space Systems Design and Test Laboratory and Radio Frequency Electronics Laboratory of Istanbul Technical University (ITU) in collaboration with the Türksat company along with Turkish Amateur Satellite Technology Organization (TAMSAT). It was launched on 26 April 2013.
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.
Dove-OSCAR 17 is a Brazilian educational and amateur radio satellite (BRAMSAT) (AMSAT-BRAZIL) launched on 22 January 1990.
ParkinsonSAT, PSat or Naval Academy OSCAR 84 is a U.S. technology demonstration satellite and an amateur radio satellite for Packet Radio. It was built at the U.S. Naval Academy and was planned as a double satellite. The name ParkinsonSAT was chosen in honor of Bradford Parkinson, the father of the GPS system. After successful launch, the satellite was assigned the OSCAR number 84.
BRICSat-P or OSCAR 83 (NO-83) previously known as PSat-B, is a U.S. technology demonstration satellite and an amateur radio satellite for Packet Radio. BRICSat-P is a low cost 1.5U CubeSat built by the U.S. Naval Academy Satellite Lab in collaboration with George Washington University, that will demonstrate on-orbit operation of a Micro-Cathode Arc Thruster (µCAT) electric propulsion system and carries an amateur communication payload.
PSAT-2 is an experimental amateur radio satellite from the U.S. Naval Academy, which was developed in collaboration with the Technical University of Brno in Brno, Czech Republic. AMSAT North America's OSCAR number administrator assigned number 104 to this satellite; in the amateur radio community it is therefore also called Navy-OSCAR 104, short NO-104.
OSCAR 8 is an American amateur radio satellite. It was developed and built by radio amateurs of the AMSAT and launched on March 5, 1978 as a secondary payload together with the earth observation satellite Landsat 3 from Vandenberg Air Force Base, California, United States.
Eyesat-1 is an American experimental communications microsatellite with an store-dump payload. The mission of Eyesat-1 was experimental monitoring of mobile industrial equipment. Eyesat-1 has provided the National Oceanic and Atmospheric Administration in Silver Spring, Maryland, with communication services to the South Pole. Eyesat-1 carries an FM repeater for Amateur Radio Research and Development Corporation (AMRAD) called AMRAD OSCAR 27 or OSCAR 27.
OSCAR 44 is an American amateur radio satellite for packet radio. It was built by Bob Bruninga at the U.S. Naval Academy.
SAPPHIRE was a satellite built by the Stanford University students in Palo Alto, California.
Starshine 3 is one of five satellites in the Starshine project.
Radar Fence Transponder was an amateur radio satellite that was developed and built for training purposes at the United States Naval Academy. The 3 kg (6.6 lb) heavy RAFT had a cubic structure of 12.7 cm (5.0 in) edge length and therefore did not meet the Cubesat standard. Solar cells on all six sides of the satellite were used to supply energy. It had neither position control nor drive systems.
HADES, Spain-OSCAR 115 or SO-115, is a Spanish amateur radio satellite. HADES was designed and built jointly by AMSAT-EA and students from the European University of Aerospace Engineering in Madrid, Spain. The satellite is a PocketQube form factor 1.5P nano-satellite and carries an FM repeater. Another payload comes from the University of Brno and consists of a miniature camera module that transmits the captured images as an audio signal in SSTV mode. The SSTV formats it uses are compatible with Robot36, Robot72, MP73 and MP115. This design is based on that of PSAT-2.
