CubETH
CubETH is a Swiss satellite project. As of 2015, it is being developed by several Swiss academic and industrial partners. The spacecraft is a single unit CubeSat and therefore 10 x 10 x 10 cm (3.9 x 3.9 x 3.9 in) in size. Its main goal is to prove the feasibility of attitude and orbit determination with low cost commercial off-the-shelf GNSS-receivers. Aims CubETH is a technology demonstration mission. The first goal is to prove that low cost receivers can be used for positioning in space. The orbit as well as the attitude of the spacecraft will be computed on board the satellite and send to a station on earth. The post-processing of the data will allow a first plausibility check. In order to fulfil an external validation, CubETH will be equipped with satellite laser ranging reflectors for range measurements from ground stations. Satellite structure The upper face of the satellite will be equipped with four GNSS antennas. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Risk Assessment
Broadly speaking, a risk assessment is the combined effort of: # identifying and analyzing potential (future) events that may negatively impact individuals, assets, and/or the environment (i.e. hazard analysis); and # making judgments "on the tolerability of the risk on the basis of a risk analysis" while considering influencing factors (i.e. risk evaluation). Put in simpler terms, a risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. Need Individual risk assessment Risk assessment are done in individual cases, including patient and physician interactions. Individual judgements or assessments of risk may be affected by psychological, ideological, religious or otherwise subjective factors, which impa ...

CubeSats
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, and ...

List Of CubeSats
The following is a list of CubeSats, nanosatellites used primarily by universities for research missions, typically in low Earth orbits. Some CubeSats became their country's first national satellite. The extensivNanosatellite and CubeSat Databaselists nearly 4,000 CubeSats and NanoSats have been launched since 1998. The organization forecasts that 2080 nanosats will launch within the next 6 years. Research and development * SBUDNIC was launched to test Arduino Nano and other commercial off-the-shelf technology in space, using a simple, open-source design. * An ambitious project is the QB50, an international network of 50 CubeSats for multi-point by different universities and other teams, ''in-situ'' measurements in the lower thermosphere (90–350 km) and re-entry research. QB50 is an initiative of the von Karman Institute and is funded by the European Union. Double-unit ("2-U") CubeSats (10x10x20 cm) are foreseen, with one unit (the 'functional' unit) providing the usual sat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solar Panel
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or grid-connected photovoltaic system, feeds power back into an alternate current (AC) electric grid, grid via an solar inverter, inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. ...

Satellite Laser Ranging
In satellite laser ranging (SLR) a global network of observation stations measures the round trip time of flight of ultrashort pulses of light to satellites equipped with retroreflectors. This provides instantaneous range measurements of millimeter level precision which can be accumulated to provide accurate measurement of orbits and a host of important scientific data. The laser pulse can also be reflected by the surface of a satellite without a retroreflector, which is used for tracking space debris. Satellite laser ranging is a proven geodetic technique with significant potential for important contributions to scientific studies of the earth/atmosphere/ocean system. It is the most accurate technique currently available to determine the geocentric position of an Earth satellite, allowing for the precise calibration of radar altimeters and separation of long-term instrumentation drift from secular changes in ocean topography. Its ability to measure the variations over time in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
