SATELLITE Conference :: Engineering
Engineering: CTO Roundtable Breakfast |
 |
With satellites playing an increasingly vital role in the management and transmission of both military and enterprise information, the security of these network infrastructures becomes even more vital. Satellite operators and service providers have learned from past security breaches to avoid more crippling attacks against their networks and keep up with the skill and knowledge of those that are responsible for these breaches. This CTO roundtable aims to explore network security issues and answer questions pertaining to future challenges. Is having the right equipment, encryption systems a and software enough to protect a network? How have network protection methods advanced in recent years and how will they continue to evolve?

The Never-ending Modernization of GPS |
|
The Global Positioning System (GPS) is a capability that almost everyone in the United States uses on a daily basis. The same could be said for Russia's Glonass system and will someday be said for the European Galileo system. While the associated applications are common knowledge, the advancement and modernization of GPS is a constant, ongoing mission for engineers. This panel will explore the detailed elements of the GPS constellation and discuss theories of navigation and time measurement, future additional signals, laser reflectors and interference issues.

Quest to Defy Physics: Ka-band and Rain Attenuation |
|
The launch of several Ka-band exclusive satellites has brought new possibilities to the commercial broadband market. With high-throughput spot beams dramatically increasing transmission speeds, there seems to be no limit to Ka-band's potential - except physics. One of the biggest obstacles to the growth of the Ka-band business is rain attenuation, or rain fade. While some providers and operators have surrendered high rainfall regions to other bandwidths, others have taken up the task of defying physics and conquering rain fade. But is this even possible? This panel will discuss availability and attenuation allocation, rain models and mitigation methods and stress the importance of accounting for rain attenuation in satellite communication design.

High Throughput and Beyond: Exploring Future Bandwidths and Applications |
|
The utilization of satellite bandwidth continues to evolve to meet the demand of cutting edge applications. For example, the insatiable thirst for high-throughput broadband has driven the widespread adoption of spot-beam Ka-band and the optimization of wide-beam C- and Ku-band to match and exceed modern performance standards. This panel aims to explore the track of this evolution heading into the future and answer two main questions. To what degree can current bandwidths be enhanced? And, what lies beyond our current bandwidth resources that could emerge as a viable resource and eventually, a viable market for satellite operators? [more] |

LightSquared and GPS: Status Update and Lessons Learned |
|
In January 2011 the U.S. Federal Communications Commission (FCC) granted a waiver to In January 2011 the U.S. Federal Communications Commission (FCC) granted a waiver to LightSquared to operate a broadband terrestrial network that would use a portion of L-band spectrum adjacent to the L-band frequencies used by the Global Position System (GPS). The waiver was granted on the condition that LightSquared would not interfere with GPS signals. Various components of the GPS community, including the Department of Defense (DoD) and receiver manufacturers, have raised concerns that the LightSquared network would significantly degrade the performance of GPS. LightSquared reached an agreement with Inmarsat in June 2011 to accelerate its acquisition of the operator's lower block of spectrum to move further away from the GPS bandwidth, but the interference questions remained.The panel of experts will discuss this controversial issue and report on the technical results of measurements performed in laboratory simulations to answer the questions, Would the proposed LightSquared network interfere with GPS? and What alternatives might be possible?

Network Security: Safeguarding Satellite Operations |
|
A layered and tested approach with multiple levels of security is required to protect satellite networks against cyber attacks that can culminate in malicious data corruption, system and service disruptions, and unauthorized information disclosure. This panel will review the threats to your network, what tests you can run to see how secure your network is and, more importantly, what procedures you can implement today for safeguarding your satellite network into the future.

Methods for Improving Satellite Bandwidth Efficiency |
|
There is a significant need to increase satellite bandwidth efficiency. There has been a growing demand for higher data rates to support advanced broadcast systems, such as high definition television delivered by satellite, and higher data rate, lower cost transmission of point to point internet files and streams. This session will explore techniques that have been developed to fit more data into the available satellite bandwidth, both to increase the bits per second per hertz, and to decrease the cost per bit per second. Two major trends will be discussed: The use of advanced methods of modulation and coding, the development of more powerful satellites that employ frequency reuse by means of spot beams which enable higher levels of satellite capacity. The expert panel will discuss the current state of the art and what might be expected in the near future. [more] |

New Methods of Antenna Design |
|
The antenna is the interface between the Earth station or satellite and free space. Its function is to focus the radiation and direct the communications signal in the desired direction. As the size of the antenna increases, the gain increases and the bandwidth decreases. This session will explore the technologies of various types of antennas. The methods used to reduce sidelobes and improve efficiency will be discussed. The radiation pattern must conform to regulatory standards. The technical advantages of phased array antennas will be compared with those of the usual parabolic antennas, including relative cost and performance. [more] |
