3D Printing
3D printing or additive manufacturing is the Manufacturing, construction of a three-dimensional object from a computer-aided design, CAD model or a digital 3D modeling, 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under Computer Numerical Control, computer control, with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source Hardware
Open-source hardware (OSH) consists of physical artifacts of technology designed and offered by the open-design movement. Both free and open-source software (FOSS) and open-source hardware are created by this open-source culture movement and apply a like concept to a variety of components. It is sometimes, thus, referred to as FOSH (free and open-source hardware). The term usually means that information about the hardware is easily discerned so that others can make it – coupling it closely to the maker movement. Hardware design (i.e. mechanical drawings, schematics, bills of material, PCB layout data, HDL source code and integrated circuit layout data), in addition to the software that drives the hardware, are all released under free/libre terms. The original sharer gains feedback and potentially improvements on the design from the FOSH community. There is now significant evidence that such sharing can drive a high return on investment for the scientific community. It is n ...

Ground Stations
A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of the Earth, or in its atmosphere. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link. A principal telecommunications device of the ground station is the parabolic antenna. Ground stations may have either a fixed or itinerant position. Article 1 § III of the International Telecommunication Union (ITU) Radio Regulations describes various types of stationary and mobile ground stations, and their interrel ...

UPSat
UPSat was the first satellite manufactured in Greece to be successfully launched into orbit, by the University of Patras and Libre Space Foundation (an earlier Greek-made communications satellite, HELMARS-SAT, although entirely constructed by 1999, was not launched due to budget limitations). It was part of the QB50 mission with ID GR-02. The UPSat mission was the first satellite launched into orbit made entirely of open-source software and open-source hardware. Open-source The UPSat mission developed an open-source hardware and software 2U cubesat, minimizing the use of commercial off the shelf components, and providing hardware and software designs under the provisions of the CERN-OHLv2 and GNU-GPLv3 licenses respectfully. The vast majority of its components were designed from scratch in an open-source software and hardware way. Mission UPSat, as part of the QB50 cubesat constellation, was launched to the International Space Station at April 18, 2017 11:11 EDT at Cape Cana ...

CubeSat
A CubeSat is a class of miniaturized satellite based around a form factor consisting of cubes. CubeSats have a mass of no more than per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. , more than 1,600 CubeSats have been launched. In 1999, California Polytechnic State University (Cal Poly) professor Jordi Puig-Suari and Bob Twiggs, a professor at Stanford University Space Systems Development Laboratory, developed the CubeSat specifications to promote and develop the skills necessary for the design, manufacture, and testing of small satellites intended for low Earth orbit (LEO) that perform a number of scientific research functions and explore new space technologies. Academia accounted for the majority of CubeSat launches until 2013, when more than half of launches were for non-academic purposes, ...

OPS-SAT
OPS-SAT is a CubeSat by the European Space Agency (ESA) and it is intended to demonstrate the improvements in mission control capabilities that will arise when satellites can fly more powerful on-board computers. The mission has 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 satellite has an experimental computer that is ten times more powerful than traditional ESA on-board computers. This on-board computer provides an experimental platform to run software experiments on board. One innovative concept is the deployment of space software in the form of apps. This concept is enabled by the NanoSat MO Framework (NMF) and allows Apps to be uploaded to the spacecraft and then started on board. This is a new concept that ESA has successfully demonstrated in space. OPS-SAT has been launched at 08:54:20 UTC on 18 December 2019 exactly twenty-four hours later than originally plann ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hackaday
''Hackaday'' is a hardware hacking website. It was founded in 2004 as a web magazine. Since 2014, Hackaday also hosts a community database of open-source hardware designs. History Hackaday was founded in 2004 by Phillip Torrone as a web magazine for Engadget, devoted to publishing and archiving "the best hacks, mods and DIY projects from around web". Hackaday was since split from Engadget and its former parent company Weblogs, Inc. by its at the time owner Jason Calacanis.
