Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy.
The Mobile User Objective System (MUOS) is a United States Space Force narrowband military communications satellite system that supports a worldwide, multi-service population of users in the ultra high frequency (UHF) band. The system provides increased communications capabilities to newer, smaller terminals while still supporting interoperability with legacy terminals. MUOS is designed to support users who require greater mobility, higher bit rates and improved operational availability. The MUOS was declared fully operational for use in 2019.
FalconSAT is the United States Air Force Academy's (USAFA) small satellite engineering program. Satellites are designed, built, tested, and operated by Academy cadets. The project is administered by the USAFA Space Systems Research Center under the direction of the Department of Astronautics. Most of the cadets who work on the project are pursuing a bachelor of science degree in astronautical engineering, although students from other disciplines join the project.
The Bion satellites, also named Biocosmos, is a series of Soviet biosatellites focused on space medicine.
Kosmos 936 or Bion 4 was a Bion satellite. The mission involved nine countries in a series of biomedical research experiments. The experiments were primarily follow-ups to the Bion 3 flight. Scientists from the Bulgaria, Czechoslovakia, East Germany, France, Hungary, Poland, Romania, the United States and the Soviet Union conducted experiments in physics and biology on the mission.
NanoSail-D2 was a small satellite built by NASA's Marshall Space Flight Center and Ames Research Center to study the deployment of a solar sail in space. It was a three-unit CubeSat, measuring 30 cm × 10 cm × 10 cm with a mass of 4 kg (8.8 lb). Its solar sail had an area of 10 m2 (110 sq ft), and was deployed in around five seconds.
F-1 is a CubeSat built by FSpace laboratory at FPT University, in Hanoi, Vietnam, in partnership with Angstrom Space Technology Center (ASTC), Uppsala University, Sweden and Nanoracks LLC, United States. Its mission is to train young engineers and students about aerospace engineering and evaluate an advanced three-axis magnetometer, Spin-Dependent Tunneling Magnetometer (SDTM) designed in Sweden by ASTC.
KickSat was a satellite dispenser for small-satellite (femtosatellite) project inaugurated in early October 2011, to launch many very small satellites from a 3U CubeSat. The satellites have been characterized as being the size of a large postage stamp. and also as "cracker size". The mission launch was originally scheduled for late 2013 and was launched April 18, 2014.
Technology Education Satellite (TechEdSat) is a successful nano-sat flight series conducted from the NASA Ames Research Center in collaboration with numerous universities. While one of the principal aims has been to introduce young professionals and university students to the practical realm of developing space flight hardware, considerable innovations have been introduced. In addition, this evolving flight platform has tested concepts for Low Earth Orbit (LEO) sample return, as well as planetary nano-sat class mission concepts.
Codec 2 is a low-bitrate speech audio codec that is patent free and open source. Codec 2 compresses speech using sinusoidal coding, a method specialized for human speech. Bit rates of 3200 to 450 bit/s have been successfully created. Codec 2 was designed to be used for amateur radio and other high compression voice applications.
OSCAR 3 is the third amateur radio satellite launched by Project OSCAR into Low Earth Orbit. OSCAR 3 was launched March 9, 1965 by a Thor-DM21 Agena D launcher from Vandenberg Air Force Base, Lompoc, California. The satellite, massing 15 kg (33 lb), was launched piggyback with seven United States Air Force satellites. Though the satellite's active life was limited to sixteen days due to battery failure, OSCAR 3 relayed 176 messages from 98 stations in North America and Europe during its 274 orbit life-time -- the first amateur satellite to relay signals from Earth. As of 2023, it is still in orbit.
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.
Bion-M No.1 (Бион-М) was a Russian space mission, part of the Bion-M programme focused on space medicine. The new generation Bion-M continued the Soviet/Russian Bion satellite programme aimed at biological research in space. The last spacecraft of the Bion series, Bion 11, was launched in 1996. The Bion-M1 spacecraft was designed to carry biological, physiological and biotechnological experiments to low Earth orbit and return them to Earth at the end of the mission. The biological payload for Bion-M1 included rodents, amphibians, reptiles, crustaceans, mollusks, fish, insects, bacteria, plant and animal cell cultures. The spacecraft was the result of collaboration hosting biomedical payloads provided by scientific institutions from the United States, Germany, Canada, the Netherlands, Poland and other countries. The Bion-M automated spacecraft was a unique specialized space complex that aimed to determine the fundamental mechanisms of how life adapts to microgravity and then readapts to Earth-normal gravity.
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 28 February 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 28 July 2014.
OSCAR 1 is the first amateur radio satellite launched by Project OSCAR into low Earth orbit. OSCAR I was launched December 12, 1961, by a Thor-DM21 Agena B launcher from Vandenberg Air Force Base, Lompoc, California. The satellite, a rectangular box weighing 10 kg., was launched as a secondary payload (ballast) for Corona 9029, also known as Discoverer 36, the eighth and final launch of a KH-3 satellite.
OPS-SAT was a CubeSat by the European Space Agency (ESA), intended to demonstrate the improvements in mission control capabilities that will arise when satellites can fly more powerful on-board computers. The mission had the objective to break the cycle of "has never flown, will never fly" in the area of satellite control. It was the first CubeSat operated directly by ESA.
The NanoSat MO Framework (NMF) is an open-source software framework for small satellites based on CCSDS Mission Operations services.
