LituanicaSAT-1 FM Repeater Board
LituanicaSAT-1 was one of the first two Lithuanian satellites (other one being LitSat-1). It was launched along with the second Cygnus spacecraft and 28 Flock-1 CubeSats aboard an Antares 120 carrier rocket flying from Pad 0B at the Mid-Atlantic Regional Spaceport on Wallops Island to the International Space Station. The launch was scheduled to occur in December 2013, but later was rescheduled to 9 January 2014 and occurred then. The satellite was broadcasting greetings of Lithuanian president, Mrs. Dalia Grybauskaitė. The satellite was deployed from the International Space Station via the NanoRacks CubeSat Deployer on February 28, 2014. All LituanicaSAT-1 subsystems have been turned on, tested and proved to be working properly. The mission is considered a complete success by its team of engineers. The mission ended upon the reentry and disintegration of the satellite on July 28, 2014. Description The satellite conforms to standard 1U size cubesat form factor as to the ...

Vilnius University
Vilnius University ( lt, Vilniaus universitetas) is a public research university, oldest in the Baltic states and in Northern Europe outside the United Kingdom (or 6th overall following foundations of Oxford, Cambridge, St. Andrews, Glasgow and Aberdeen). Today it is Lithuania's leading academic institution, ranked among the top 400 ( QS) or top 800 ( ARWU) universities worldwide. As of 2022 QS ranks VU as 8th in CEE (ex. Russia); an ARWU equivalent would be 11th. The university was founded in 1579 as the Jesuit Academy (College) of Vilnius by Stephen Báthory, Grand Duke of Lithuania and King of Poland. It was the third oldest university (after the Cracow Academy and the Albertina) in the Polish–Lithuanian Commonwealth. Due to the failure of the November Uprising (1830–1831), the university was closed down and suspended its operation until 1919. In the aftermath of World War I, the university saw failed attempts to restart it by the local Polish Society of Friends of Scie ...

Cubesat
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, ...

Amateur Radio Station
An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations. A slang term often used for an amateur station's location is the shack, named after the small enclosures added to the upperworks of naval ships to hold early radio equipment and batteries. ;See also: Types of stations Fixed stations An amateur radio station established in a permanent structure with equipment that is not intended for portable operation is referred to as a ''fixed station''. This is the most common form of amateur radio station, and can be found in homes, schools, and some public buildings. A typical fixed station is equipped with a transceiver and one or more antennas. For voice communications, the station will be equipped with a microphone; for commu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...

ATMega2560
AVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to one-time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time. AVR microcontrollers find many applications as embedded systems. They are especially common in hobbyist and educational embedded applications, popularized by their inclusion in many of the Arduino line of open hardware development boards. History The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH), Alf-Egil Bogen and Vegard Wollan.Archived aGhostarchiveand thWayback Machine Atmel says that the name AVR is not an acronym and does not stand for anything in particular. The creators of the AVR give no definitive answer as to what the term "AVR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
