Delfi-C3
Delfi-C3 is a CubeSat satellite constructed by students at the Delft University of Technology in the Netherlands. It is a 3-unit CubeSat, and was launched at 03:53:42 on 28 April 2008, as part of the NLS-4 mission, aboard a PSLV rocket, from the Second Launch Pad at the Satish Dhawan Space Centre in India. The launch was contracted by ISRO, through Antrix Corporation and UTIAS. The satellite's primary mission is technology demonstration and development. It is carrying new types of solar cells, a solar sensor for TNO Science and Industry, and a high-efficiency amateur radio transceiver experiment. Delfi-C3 does not contain batteries, as the experiments are dependent on the sun. She is the fourth Dutch Satellite, after ANS, IRAS and SLOSHSAT. It is the first Dutch university Satellite and is based on a 3-Unit CubeSat. Some other mission characteristics include: * No active attitude control * 1200Bd BPSK VHF downlink * Linear transponder The Delfi-C3 ground segment consists of ...

COMPASS-1
Compass-1 (also known as Compass One) is a German amateur CubeSat picosatellite, built and operated in the late 2000s by Aachen University of Applied Science. It was launched by the Indian Space Research Organisation, aboard a PSLV rocket as a secondary payload to the CartoSat-2A primary spacecraft on 28 April 2008. It was launched into a Geocentric orbit with an altitude of 597 km. Its primary mission is remote sensing; however, it also contains some technology demonstration experiments regarding the use of small satellites and GPS tracking. On 10 August 2008, the satellite developed a problem and switched into "emergency mode". Initial attempts to rectify this problem failed; however, normal operations were resumed on 10 September, with help from amateur radio operators around the world. Overview Most of the objectives for Compass-1 were focused on the evaluation and testing of CubeSats and new technologies. It was made using scratch-built software, hardware, and parts, e ...

AAUSAT-II
AAUSAT-II (Aalborg University CubeSat no 2), is the second student-built CubeSat built and operated by students from Aalborg University in Denmark. It was launched 28 April 2008 05:53:51 UTC from Satish Dhawan Space Centre in India on a Polar Satellite Launch Vehicle (PSLV) launch vehicle. AAUSAT-II carries a gamma radiation sensor. Educational objective The primary purpose of construction of satellites at the University of Aalborg is to give the students engineering capabilities beyond what is normally achieved within a masters program. History Student satellite activities at Aalborg University (AAU) started in 2003 as a result of AAU's involvement in the first pure Danish research satellite, Ørsted, which was successfully launched in 1999. AAUSAT-II's predecessor was AAU CubeSat which was constructed in the period 2001-2003 and was launched 30 June 2003. The project started in the summer 2003. The construction of AAUSAT-II began in 2005. Operations After the launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communication Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satelli ...

Iridium Satellite LLC
Iridium Communications Inc. (formerly Iridium Satellite LLC) is a publicly traded American company headquartered in McLean, Virginia. Iridium operates the Iridium satellite constellation, a system of 66 active satellites and 9 in-orbit spares used for worldwide voice and data communication from hand-held satellite phones and other transceiver units. The nearly polar orbit and communication between satellites via inter-satellite links provide global service availability. History The Iridium communications service was launched on November 1, 1998, formerly known as Iridium SSC. The first Iridium call was made by Vice President of the United States Al Gore to Gilbert Grosvenor, the great-grandson of Alexander Graham Bell and chairman of the National Geographic Society. Motorola provided the technology and major financial backing. The logo of the company represents the Big Dipper. The company derives its name from the chemical element iridium, which has an atomic number of 77, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Polar Satellite Launch Vehicle
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO). Some notable payloads launched by PSLV include India's first lunar probe Chandrayaan-1, India's first interplanetary mission, Mars Orbiter Mission (Mangalyaan) and India's first space observatory, Astrosat. PSLV has gained credibility as a leading provider of rideshare services for small satellites, owing to its numerous multi-satellite deployment campaigns with auxiliary payloads, usually ride-sharing along with an Indian primary payload. As of June 2022, PSLV has launched 345 foreign satellites from 36 countries. Most notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
