A low-noise block downconverter (LNB) is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish and converts them to a signal which is sent through a cable to the receiver inside the building.
Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. [1] Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products.
The PhoneSat bus was used in several other projects. The follow-on project, Edison Demonstration of Smallsat Networks (EDSN), was an 8-satellite constellation of 1.5-U cubesats [8] based on the PhoneSat 3.0 architecture. However, EDSN did not make orbit, launching on the failed Super Strypi mission in November 2015. KickSat also used PhoneSat ...
The most basic repeater consists of an FM receiver on one frequency and an FM transmitter on another frequency usually in the same radio band, connected together so that when the receiver picks up a signal, the transmitter is keyed and rebroadcasts whatever is heard. In order to run the repeater a repeater controller is necessary.
Amateur-satellite service (also: amateur-satellite radiocommunication service) is – according to Article 1.57 of the International Telecommunication Union's (ITU) Radio Regulations (RR) [12] – defined as «A radiocommunication service using space stations on earth satellites for the same purposes as those of the amateur service.»
A satellite finder (or sat finder) is a satellite field strength meter used to accurately point satellite dishes at communications satellites in geostationary orbit. [ 14 ] [ 15 ] [ 16 ] Professional satellite finder meters allow better dish alignment and provide received signal parameter values as well.
A satellite modem is not the only device needed to establish a communication channel. Other equipment that is essential for creating a satellite link include satellite antennas and frequency converters. Data to be transmitted are transferred to a modem from data terminal equipment (e.g. a computer).
A radio transmitter design has to meet certain requirements. These include the frequency of operation, the type of modulation, the stability and purity of the resulting signal, the efficiency of power use, and the power level required to meet the system design objectives. [1]
