KITSAT-1
KITSAT-1 or KITSAT-A (Korean Institute of Technology Satellite) is the first satellite to be launched for the South Korea. Once launched, the satellite was given the nickname "Our Star" ( 우리별). The KITSAT-1 is a low Earth orbit (LEO) satellite with a modular structure. Of the 12 satellites launched by South Korea, KITSAT-1 has the highest altitude. While the KITSAT-1 maintains equilibrium by gravity gradient forces, magnetic torque can be used to control attitude if needed. The forecasted lifespan of the KITSAT-1 was only five years, but communication with the satellite was maintained for 12 years. Since the launch of the KITSAT-1, South Korea has launched an additional 36 satellites. Size The KITSAT-1 is considered to be a small-sized or microsatellite. The KITSAT-1 is the smallest sized low Earth orbit satellite that has been launched by South Korea. On-Board Computer System The KITSAT-1's On-board computer (OBC) system uses an OBC186 for the main OBC and an OBC80 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PoSAT-1
PoSAT-1, the first Portuguese satellite, was launched into orbit on 26 September 1993, on the 59th flight of the Ariane 40 launch vehicle. The launch took place in the Centre Spatial Guyanais, French Guiana. About 20 minutes and 35 seconds after launch, at an altitude of 807 km, PoSAT-1 separated itself from the launch vehicle. The PoSAT-1 weighs about 50 kg and belongs to the class of microsatellites, which are between 10 and 100 kg. The entire project was developed by a consortium of universities and companies in Portugal and was built at the University of Surrey, United Kingdom. The total cost was around €5 million, about €3 million paid by the Portuguese Government and €2 million by the Portuguese companies involved (Po-SAT consortium: Instituto Nacional de Engenharia, Tecnologia e Inovação (INETI), EFACEC, ALCATEL, Marconi Company, OGMA, Instituto Superior Técnico (IST), University of Beira Interior (UBI) and CEDINTEC). The responsible for the project was Fernando ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology Demonstration
A technology demonstration (or tech demo), also known as demonstrator model, is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users. Computers and gaming Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development. * Computer game developers use tech demos to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing.

Small Satellite
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multipl ...

Satellites Of South Korea
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, ...

Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants.
