The TracVision UHD7 is a high-performance 60 cm (24 inch) marine satellite TV antenna designed to provide boat owners, charter yacht guests, and commercial vessel crews access to ultra-high-definition (UHD) and 4K programming from leading satellite TV providers.
The Maritime Monitoring and Messaging Microsatellite (M3MSat) is a tele-detection satellite developed by the Canadian Space Agency and launched in 2016. Its mission is to demonstrate and test the technology to assess the utility of having in space an Automatic Identification System (AIS) for reading signals from vessels to better manage marine transport in Canadian waters.

In 1976 Taylor Howard built an amateur system, which consisted of a converted military surplus radar dish and a satellite receiver designed and built by Howard, for home satellite reception. Taylor's system could be used for receiving TV programs both from American and Soviet communication satellites.
A QPSK Digital Satellite Headend by Fracarro. A SMATV headend is used to receive and rebroadcast satellite television channels throughout a property from a single satellite feed. [4] The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5]
Special LNBs have been developed for use in single-cable distribution systems. All four sub-bands of the Ku band (low frequency/horizontal polarity, high frequency/horizontal polarity, low frequency/vertical polarity, high frequency/vertical polarity) are received by a conventional front end, amplified and downconverted to the L-band, to be fed to a number of SatCR (Satellite Channel Router ...
Television receive-only (TVRO) is a term used chiefly in North America, South America to refer to the reception of satellite television from FSS-type satellites, generally on C-band analog; free-to-air and unconnected to a commercial DBS provider.
PAF, or phase alternating by field (like the first NTSC color system trial) was also experimented with, and it gave much better decoding results, but NHK abandoned all composite encoding systems. Because of the use of satellite transmission, Frequency modulation (FM) should be used with power-limitation problem. FM incurs triangular noise, so ...
The prevention of piracy on cable and satellite networks has been one of the main factors in the development of Pay TV encryption systems. The early cable-based Pay TV networks used no security. This led to problems with people connecting to the network without paying. Consequently, some methods were developed to frustrate these self-connectors ...
