UniBRITE-1
UniBRITE-1 is, along with TUGSAT-1, one of the first two Austrian satellites to be launched. Along with TUGSAT, it operates as part of the BRIght Target Explorer constellation of satellites. The two spacecraft were launched aboard the same rocket, an Indian PSLV-CA, in February 2013. UniBRITE is an optical astronomy spacecraft operated by the University of Vienna as part of the BRIght Target Explorer programme. Features UniBRITE-1 was manufactured by thSpace Flight Laboratory (SFL)of the University of Toronto Institute for Aerospace Studies (UTIAS), based on the Generic Nanosatellite Bus, and had a mass at launch of (plus another 7 kg for the XPOD separation system). The satellite will be used, along with five other spacecraft, to conduct photometric observations of stars with apparent magnitude of greater than 4.0 as seen from Earth.

BRITE
BRITE-Constellation is an ongoing space mission carrying out two-band photometry in wide fields with a constellation of six (presently, three operational) BRIght Target Explorer (BRITE) nanosatellites. The mission was built by a consortium of three countries, Canada, Austria, and Poland, each operating two BRITE satellites. The six satellites were launched into low-Earth orbits between February 2013 and August 2014. Each satellite is a cube-shaped spacecraft with sides of hosting an optical telescope of aperture feeding an uncooled CCD with a field of view of approximately 20° × 24°. The satellites were intended for photometry of the brightest stars in single passband located in the blue (three satellites) or red (the other three satellites) part of the optical range. Early history The idea of using microsatellite for scientific observations, especially for photometry of bright stars, was born during discussions on possible designs for Canada's first scientific satellite.

Sapphire (satellite)
Sapphire is a Canadian space surveillance satellite which was launched in 2013. Sapphire was commissioned and integrated by MacDonald, Dettwiler and Associates (MDA) based on an SSTL-150 bus produced by Surrey Satellite Technology (SSTL) and an optical payload produced by COM DEV International. Details Sapphire, Canada's first military satellite, is a small spacecraft designed to monitor space debris and satellites within an orbit 3,728 to 24,855 miles (6,000 to 40,000 kilometres) above Earth. The satellite has been providing data to the United States Space Surveillance Network since January 2014. The satellite has a mass of , and carries a three-mirror anastigmat to track artificial objects in medium Earth orbit to geosynchronous Earth orbit. ISRO's Ball Lock separation system IBL-298 was used for separating the satellite. The optical system is based on the design of the Space-Based Visible (SBV) sensor. This telescope was developed for the Midcourse Space Experiment. The C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SARAL
SARAL (''S''atellite with ''AR''gos and ''AL''tiKa) is a cooperative altimetry technology mission of Indian Space Research Organisation (ISRO) and Centre National d'Études Spatiales (CNES). SARAL performs altimetric measurements designed to study ocean circulation and sea surface elevation. Mission A CNES / ISRO MOU ( Memorandum of Understanding) on the SARAL mission was signed on 23 February 2007. The SARAL mission is complementary to the Jason-2 mission of NASA / NOAA and CNES / EUMETSAT. It will fill the gap between Envisat and the Sentinel-3 mission of the European Copernicus Programme (Global Monitoring for Environment and Security - GMES programme). The combination of two altimetry missions in orbit has a considerable impact on the reconstruction of sea surface height (SSH), reducing the mean mapping error by a factor of 4. Instruments The SARAL payload module was provided by CNES: ALtiKa (Ka-band altimeter), Doppler Orbitography and Radiopositioning Integrated by ...

University Of Vienna
The University of Vienna (german: Universität Wien) is a public research university located in Vienna, Austria. It was founded by Duke Rudolph IV in 1365 and is the oldest university in the German-speaking world. With its long and rich history, the university has developed into one of the largest universities in Europe, and also one of the most renowned, especially in the Humanities. It is associated with 21 Nobel prize winners and has been the academic home to many scholars of historical as well as of academic importance. History From the Middle Ages to the Enlightenment The university was founded on March 12, 1365, by Rudolf IV, Duke of Austria, hence the name "Alma Mater Rudolphina". After the Charles University in Prague and Jagiellonian University in Kraków, the University of Vienna is the third oldest university in Central Europe and the oldest university in the contemporary German-speaking world; it remains a question of definition as the Charles University in Prague ...

MOST (satellite)
The Microvariability and Oscillations of Stars/Microvariabilité et Oscillations STellaire (MOST), was Canada's first space telescope. Up until nearly 10 years after its launch it was also the smallest space telescope in orbit (for which its creators nicknamed it the "Humble Space Telescope", in reference to one of the largest, the Hubble Space Telescope, Hubble). MOST was the first spacecraft dedicated to the study of asteroseismology, subsequently followed by the now-completed CoRoT and Kepler space telescope, Kepler missions. It was also the first Canadian science satellite launched since ISIS (satellite), ISIS II, 32 years previously. Description As its name suggests, its primary mission was to monitor variations in star light, which it did by observing a single target for a long period of time (up to 60 days). Typically, larger space telescopes cannot afford to remain focused on a single target for so long due to the demand for their resources. At , wide and tall, and dee ...

Space Telescopes
A space telescope or space observatory is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid the filtering and distortion ( scintillation) of electromagnetic radiation which they observe, and avoid light pollution which ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky (astronomical survey), and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct from Earth imaging satellites, which point toward Earth for satellite imaging, applied for weather analysis, espionage, and other types of information gathering. History Wilhelm Beer and Johann Heinrich Mädler in 1837 discussed the advantages of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellites Of Austria
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...
