From the Paper "Just as many TV viewers have come to consider cable TV a life necessity, so too is satellite radio becoming a mainstream replacement for traditional AM/FM listening. Similar to cable, this service has to be paid for, but just as with cable, you get a lot more channels and edgier, more innovative programming. An additional benefit is that there is no loss of your favorite station as you travel across the state or country. As an added plus, satellite players show the artist and name of the song, which is definitely an incentive for those who like to know what they're listening to."
Abstract This paper explains that the advantage of satellite technology over direct wire transmission is obvious: Satellites can transmit data at light speed anywhere on the planet without impractical and costly wiring. The author writes about three general types of satellites, classified by the type of orbit they follow: (1) Geosynchronous orbit, GEO, in which the satellite's orbit is synchronized with the rotation of the earth; (2) Medium earth orbit, MEO, which gets closer to the earth because it utilizes an elliptical orbit, and (3) Low earth orbit, LEO, the most recent type of satellite, which are located approximately 450 miles above the surface of the Earth, and can be used for portable phones with smaller antennas. The paper relates that the attributes of satellite systems make them valuable for varying internet applications, but the primary difficulty now is congestion and associated delays; however, when LEO satellites become more abundant and dependable, it is probable that the amount of internet traffic, which LEO satellites can handle, will increase.
From the Paper "Fortunately, as the technologies improve-in both the internet and satellites-prices fall and these tools become more widely available. "Thanks to both the rapid deployment of the internet, and advances in satellite technology, the market for broadband satellite services is poised for substantial growth in the coming decade." Particularly, satellites in GEO orbits are being improved to be capable of relaying more information; with less latency and interference. Also, LEO satellites are being employed because they do not require the bulky equipment needed to improve the existing GEO satellites. Additionally, with the advent of dense wavelength division multiplexing along fiber optic cables, broadband capabilities should become exponentially greater."

Abstract The paper should look at both pros and cons of satellite TV. The television signals transmitted by a satellite are quite different from the television or radio signals that are broadcast over the air. Satellite TV is transmitted by microwaves. Microwaves don't behave like the lower frequency radio waves of off-air television or radio, which can bounce off obstructions, clouds, and the ground. Microwaves are strictly line of sight. In order for a satellite dish to receive a signal, there can be no obstruction between the transmitting satellite and the receiving satellite dish.
Abstract The paper relates that satellite imagery has affected the deforestation of the Amazon by detecting problems such as road building, mining operations, fires where land is being cleared for crops, logging operations, dam projects and clearing for building projects. The results of these satellite images also indicate rising heat indexes, less forest and damage to the ecological system that exists in the Amazon. The paper reveals how satellites determine data and offers general information about the technology.

From the Paper "The amount of water or ice particles in the air can be measured by a satellite sensor and this determines part of the information that will tell what is going on, back on earth. Together with satellite visual imagery, the information can give a scientist an amazing amount of information. An article in Satellite Data Applications: Weather and Climate talks about how satellites may measure the physically based parameterization of cloud processes and cloud water. (Weng 407) These measurements are used in a SSMI/Cloud Liquid Water algorithm to find out how the clouds are affected by the thermal emission. (Earth 2005)"
Abstract In this article, the writer first defines core-satellite management and then discusses the efficency of the core-satellite portfolio model.

Conclusion
From the Paper "The goal of the tracking error constraints is to limit the bad tracking error. However, tight tracking error constraints can lead to a suboptimal management of the portfolio.
"First, as most active managers still have dominant passive exposure to their benchmark, a great part of their fees reward a passively managed portfolio.
"Secondly, the active manager cannot use freely their skills. When an actively managed portfolio must follow a benchmark with tight tracking error constraints, it severely restricts the amount invested in active strategy. This means renouncing to opportunities of return enhancement and risk reduction. In case of economic downturn the opportunity cost is even higher because active absolute return strategies usually out-perform the market.
"With the core-satellite, on the contrary, because of the higher tracking error allowed to the satellites, the managers don't have to give up the potential of higher returns generated by selected active management strategies."

From the Paper "The technology behind the global positioning satellites system takes its origin from Marconi's comprehension of the radio waves and their utilization for transmission purposes. This radio wave technology was employed for social advantage in the course of 1920s. In these years, radio stations were established, which minimally required a receiver to commence operation. A complex model of the same simple technology applies to the functioning of the global positioning satellites system."
Abstract This paper explores satellite internet and its application in rural areas where traditional Internet connections are not possible. Satellite Internet is made possible in two different ways. A one-way satellite internet connection requires the user to have a phone line so that the request for a data download is made via the copper line and the download is sent using the satellite link up. The second type of connection involves the download request to be sent through the satellite Internet as well as the receiving information. Satellite Internet is becoming increasingly important for rural farmers as it gives them a sustainable competitive advantage. The need to access reliable and real-time agricultural information is critical to decision making and future farming success.
From the Paper "The use of satellite Internet is becoming increasingly important for farmers in remote locations allowing them to access integral information for vital decisions. Recently in the agricultural sector, uptake of such technology has seen a dramatic increase [9]. This paper will firstly discuss satellite Internet and the two types of connections: one-way and two-way connections. The way data is transmitted will be looked at as well as the associated advantages and disadvantages for each method. Then the focus will turn to the benefits these technologies can provide to farmers in rural locations."
Abstract This paper discusses the theory of global positioning satellites, illustrating the technology behind the system. The history of global positioning satellites is outlined, describing the first global positioning system, the transmission functions and the reception of information from global positioning satellites. The paper presents the advantages of the global positioning satellites system.
From the Paper "As the name suggests, the global positioning satellite system is based on satellites. It is a navigational system that comprises of a complex arrangement of satellites that orbit round the earth. Twenty-four in all, these satellites are eleven thousand nautical miles far in space. There are six dissimilar orbits wherein the satellites continually keep revolving. It takes these satellites twenty-four hours to complete two orbital revolutions round the Earth. Upon calculation, the revolutionary speed of these satellites is computed to be around 2,600 meters per second (JA-GPS.com)."

Abstract This paper examines how satellite technology is used worldwide to provide important services in the fields of research, communications and more and how one of the most popular applications of satellite technology is the development of the Global Positional System (GPS). It provides an overview of satellites and GPS, including a brief description of the principles behind satellite technology and deployment and specifically of GPS. It also covers the origins and development of GPS as well as a synopsis of its current military and civilian uses. Finally, this paper also aims to address the future of GPS technology in the private sector.
From the Paper "By 1972, the best characteristics of these satellite systems and the investigation of the steering group came together to result in the development of today's system that would be known as the NAVSTAR Global Positioning System. The program was officially approved in 1973 and by February 1978, the first experimental GPS satellites (called Block I) were being launched into space. From the beginning, GPS had to meet the radio navigation requirements of all military services as well as those of civilian users and by February 1989, the second block of GPS satellites (Block II) was launched into space. Today's GPS is now made up of twenty-four Block II and IIA satellites and one experimental satellite from Block I. (Commission 145-146)"
Abstract Iridium LLC, the world's first global satellite phone and paging company created an expensive network of 66 low-earth orbiting satellites, combined with terrestrial cellular systems, which enabled customers to communicate virtually anywhere in the world using one phone and pager, one phone number and one monthly bill. This paper discusses how satellite mobile phones work. It then discusses the failure and bankruptcy of Iridium and proposes an alternative marketing strategy.
From the Paper "One of the current problems with satellite phones is that they require direct line-of-sight with a satellite, which means that it may be difficult to use them in buildings, especially modern ones which contain a lot of metal. Because of this, satellite phones will essentially provide an outdoor, rural service. They will be complementary to land based cellular systems and not competition for them."
Abstract This paper examines how communications satellites and computer technology, have completely revolutionized modern warfare.

The First Satellites The U.S. Military and New Strategies for Defense
Practical Applications
From the Paper "Relaying information, satellites provide real-time data in regard to "hot spots" around the world. Satellites have been instrumental in maintaining the U.S. edge in Korea, providing both surveillance capabilities and also guidance for American "smart" bombs. (Harrison, 2002, p. 126) These arrangements significantly outclass North Korean Dictator Kim Jong-Il's vast armed camp of a nation. Yet "spy satellites" hardly represent the very latest and most significant aspects of the new technology. Defense itself is being changed almost beyond recognition by the use of satellites as key elements in operations as well as planning. The new wave in military thinking focuses on, "stand-off capabilities. The situation will be developed 'out of contact,' that is, by satellite and airborne sensors rather than by the armed reconnaissance of ground elements.""
Abstract This paper discusses the evolution of U.S. military satellite communications, the improvements made upon each new program and the impact on today's military. It looks at the requirements of today's military force and the main objectives of the satellite communications program.
From the Paper "For today's modern warfighter the ability to communicate effectively is the key to success on the battlefield. U S soldiers must operate covertly in unfamiliar and hostile territory and they must know where their allies are, where their enemies are and what each is doing. Today's military must be lighter, more mobile and more lethal and the improvements made in military satellite communications ..."

Benefactors of Galileo
From the Paper "Galileo is a global navigation satellite system which has been a project supported and funded by a consortium between the European Commission and the European Space Agency. European independence is the primary factor in the development of Galileo, prior to the development of Galileo Europeans had no other option but to take positions from the satellites of foreign countries. There are a total of 15 countries working in consortium on this project either directly or indirectly."
Abstract This paper focuses on how satellite television is perceived as driving cable out of business, when in fact it is merely successful due to advertising and technological incentives rather than service quality.
Abstract This paper describes the content of Sirius Satellite Radio, a subscription service, which aims to cover all aspects of the life of the consumers.
