Since the emergence of a few online casinos in 1996, the growth and popularity of the online gambling industry has skyrocketed at a phenomenal rate. There are currently thousands of online casinos generating an estimated annual revenue of over USD $7,000,000,000. If this figure is divided by 365 days, then it could be said that online casinos generate an average of well over $19,000,000 in revenue every single day. As the global internet population continues to grow, and with internet gambling expanding into numerous non-English speaking countries in Europe and Asia, it is safe to assume that the above figures...

Any object that moves around the earth has an orbit. The orbit is defined by 3 factors. The first is the shape of the orbit, which can be circular or elliptical. The second is the altitude of the orbit. The altitude is constant for a circular orbit but changes constantly for an elliptical orbit. The third factor is the angle the orbit makes with the equator. An orbit that brings the satellite over the poles or close to it has a large angle. An orbit that makes the satellite stay close to the equator has a small angle. Orbits depend...

TVRO TeleVision Receive Only TVRO was the first satellite system available for home viewing of satellite TV. It required a relatively big dish of 3 to 6 feet in diameter and worked in C-Band. Frequencies of around 4 G Hertz are called C-Band and require bigger dishes because the wave length of these frequencies is longer than in Ku-Band which requires a much smaller dish...

You are sitting at home, watching TV, and while your show is entertaining you, outside the weather is getting worse. It starts raining, the wind is getting stronger, but your Satellite Antenna is doing its work as if it is a sunny quiet day. This is the experience of most people that enjoy satellite TV; Smooth reception no matter what weather it is outside. (Of course an hurricane that can destroy your house may be capable of moving your satellite dish as well.) Bad weather doesnt do much to Satellite antenna reception. But sometimes your antenna can loose reception completely...

A satellite is built in such a way that it is as light as possible. This way it can carry more fuel with it, which increases its life in orbit. The total weight is determined by the rocket(s) that carry the satellite into space. The rocket is able to bring a certain amount of weight into orbit and this is something the manufacturer of the satellite has to take into account when designing a new satellite. In order to bring a satellite into space it needs to first enter a low earth orbit (LEO). To get into LEO the rocket...

Remember the old days of analog TV, radio, etc. Most of us do unless youre really young. And still today there are plenty of analog systems in use. Normal radio still uses analog transmission. But the digital age has begun and more and more we will use digital systems rather than analog systems. Digital transmission systems have many advantages over analog transmission systems, like higher quality of audio and video. How come digital systems can transmit higher quality signals than analog systems? The truth is that they dont. They just use some tricks to eliminate noise. Analog Transmission Systems When...

It was in October 2001 that General Motors Hughes (Parent company of Direct TV) and EchoStar Communications Corp., trader of Dish Network agreed to a merger. The new company would have improved the services for satellite TV clients by adding many HDTV channels and local channels would then be available to all satellite TV viewers. However, the US Department of Justice blocked the merger. Why did they do that? When merged the new company would serve all of the United States without any competition. As we all know, competition spurs progress and a merger would basically result in less progress....

This article may be considered science fiction, just like Arthur C. Clark once had a scientific vision about 3 satellites orbiting the earth in geostationary orbits to make global communications possible. Everything in this article is merely a scientific vision and an extrapolation of current technologies into the future. What would be the future of Satellite TV? That may seem to be a difficult question, but extrapolating what we know about the past into the future and some educated guesses, we may very well end up with a reasonable picture of what the future of satellite TV looks like. The...

A satellite dish is an antenna designed to focus on a specific broadcast source. The standard dish consists of a parabolic (bowl-shaped) surface and a central feed horn. A controller sends it through the horn, and the dish focuses the signal into a relatively narrow beam. A narrow beam is generated as the dish reflects energy from the feed horn. The dish on the receiving end can only receive information; it cannot transmit information. The receiving dish works in the exact opposite way of the transmitter. When a beam hits the curved dish, the parabola shape reflects the radio signal...
