The Crematorium II building, which contained a gas chamber and furnaces for burning corpses. Several hundred thousand Jewish men, women and children were murdered here with poison gas, and their bodies burned.
But anyway, if there are no satellites, what the h*eck is up there?
EIRP, G/T or flux density contour corresponding to the minimum performance over a coverage area.
A single point within a coverage area with highest performance (i.e., EIRP, flux density or G/T)
A decibel referenced to one watt. Expresses units of decibels above 1 W. X (dBW) = 10 log 10 (X / 1W)
A transmission link carrying information from a satellite or spacecraft to earth. Typically down links carry telemetry, data and voice.
EIRP (Effective Isotropic Radiated Power)
In a given direction, the gain of a transmitting antenna multiplied by the net power accepted by the antenna from the connected transmitter.
G/T (antenna gain-to-noise-temperature)
The ratio of the gain to the noise temperature of the antenna. Usually the antenna-receiver system figure of merit is specified. For this case the figure of merit is the gain of the antenna divided by the system noise temperature referred to the antenna terminals. The system figure of merit at any reference plane in the RF system is the same as that taken at the antenna terminals since both the gain and system noise temperature are referred to the same reference plane at the antenna terminals.
A POP is a physical interconnect location where separate telecommunications networks meet and communicate with each other.
That property of a radiated electromagnetic wave describing the time-varying direction and amplitude of the electric field vector: specifically, the figure traced as a function of time by the extremity of the vector at a fixed location in space, as observed along the direction of propagation.
A teleport is a physical location and interface between a satellite system and telecommunications networks on the ground. It includes a variety of satellite dishes, earth stations, and supporting ground equipment.
A receiver/transmitter combination which receives a signal and retransmits it at a different carrier frequency. Transponders are used in communication satellites for reradiating signals to earth stations or in spacecraft for returning ranging signals.
A ground to satellite link.
Teleports often are characterized as the ground-based infrastructure of a satellite network, but the term means different things to different people. There is a surprising amount of diversification in the field, and the term teleport covers a wide range of facilities and business models, making it challenging to pin down exact the costs ratios of doing business. In a 2007 study, the World Teleport Association (WTA) details a fractional teleport industry with many different forms of ownership, including: telephone companies, commercial operators, DTH and cable companies, satellite operators, and system integrators, and the business dynamic is different for each business. For instance, a teleport operator providing data services to thousands of maritime vessels has a completely different business model than a DTH provider broadcasting content to millions of subscribers. But while business models vary significantly, there are a few costs which are common to most teleport operators.
Independent teleport operators have been the heart of the industry since the early 1980s. Teleport operators historically have been entrepreneurs, have focused on a geographic region and, initially, were focused primarily on the media and entertainment industries. Over time, corporate entities have been built up, acquiring teleports on different continents and operating them as an integrated service offering, often with interconnecting fiber networks. In its 2004 Teleport Benchmarks study, the WTA surveyed the marketplace about factors such as revenues, technology assets in place and employment. The data was compiled in 2004 and provides good metrics for the comparison of different teleport operators. The report breaks down the operators into classifications: small, midsize, and large and found that small teleports, on average, operate 20 satellite antennas, employ 14 people, and generate $5 million in revenue per year. Midsize operators enjoyed annual revenues between $29 million and 30 million and operated 28 antenna. Employees per teleport were not available for this market segment. Large teleport operators on average had revenues of $33.4 million, operated 87 satellite antennas and employed 57 people. While there is considerable overlap, it is rare to find two teleports offering the exact menu of services.
Arqiva Satellite & Media operates an integrated teleport and fiber distribution network. The company’s 125 uplinks can bring nearly 50 different satellites into play.
