Satellite
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 p ...

SEEDS-2
The Space Engineering EDucation Satellite 2 (SEEDS-2) is a Japanese amateur CubeSat picosatellite, built and operated by Nihon University. It was launched by the Indian Space Research Organisation, aboard a PSLV rocket, on 28 April 2008. It was built to replace the SEEDS satellite, which was lost in a launch failure on a Dnepr rocket in July 2006. It carries a number of sensors to investigate the environment of space, and its own status. It also contains a voice transmitter, intended to play back messages to amateur radio operators.

STRaND-1
STRaND-1 (Surrey Training, Research and Nanosatellite Demonstrator 1) is a failed 3U CubeSat developed by Surrey University's Surrey Space Centre (SSC) and Surrey Satellite Technology (SSTL). The nanosatellite was launched into orbit on board a PSLV Rocket from India on February 25, 2013, Smartphones have flown in space before inside the International Space Station, and the computer from a PDA launched inside two Japanese CubeSats in 2006 and 2008. STRaND-1 initially operated with a conventional CubeSat computer before it was supposed to be switched over to an on-board Android-based Nexus One smartphone, but the conventional computer stopped communicating before the switch-over could start. As a result, NASA's PhoneSats (Alexander, Graham and Bell) were the first smartphone satellites to work in space, despite having been launched two months later than STRaND-1. The satellite was found broadcasting telemetry again in June 2013, after a two-month silence. There are no reports of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Near Earth Object Surveillance Satellite
The Near Earth Object Surveillance Satellite (NEOSSat) is a Canadian microsatellite using a 15-cm aperture f/5.88 Maksutov telescope (similar to that on the MOST spacecraft), with 3-axis stabilisation giving a pointing stability of ~2 arcseconds in a ~100 second exposure. It is funded by the Canadian Space Agency (CSA) and Defence Research and Development Canada (DRDC), and searches for interior-to-Earth-orbit (IEO) asteroids, at between 45 and 55 degree solar elongation and +40 to -40 degrees ecliptic latitude. Spacecraft NEOSSat is a suitcase-sized microsatellite measuring , including telescope baffle, and weighing . It is powered by gallium arsenide (GaAs) solar cells placed on all six sides of its frame; the entire spacecraft uses around 80 watts of power, with the bus core systems consuming an average of 45 watts. The spacecraft uses miniature reaction wheels for stabilization and attitude control, and magnetic torque rods to dump excess momentum by pushing again ...

Indian Space Research Organization
The Indian Space Research Organisation (ISRO; ) is the national space agency of India, headquartered in Bengaluru. It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO acts as the executive of DOS as well. ISRO is India's primary agency for performing tasks related to space-based applications, space exploration and the development of related technologies. It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites. The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru under the Department of Atomic Energy (DAE) in 1962, on the urging of scientist Vikram Sarabhai, recognising the need in space research. INCOSPAR grew and became ISRO in 1969, within DAE. In 1972, the government of India set up a Space Commissi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanosatellite
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 multip ...
