ATI presents:

An overview of commercial satellite communications hardware, operations, business and regulatory environment

This three-day introductory course has been taught to rave reviews to thousands of industry professionals for over two decades. The material is frequently updated and the course is a primer to the concepts, jargon, buzzwords, and acronyms of the industry, plus an overview of commercial satellite communications hardware, operations, and business environment.

Here is Dr. Mark R. Chartrand, course instructor, on YouTube.

Since 1984, the Applied Technology Institute (ATI) has provided leading-edge public courses and onsite technical training to DoD and NASA personnel, as well as contractors. Whether you are a busy engineer, a technical expert or a project manager, you can enhance your understanding of complex satellite systems in a short time. You will become aware of the basic vocabulary essential to interact meaningfully with your colleagues.

Here is more about the course.

SATELLITE COMMUNICATIONS COURSE — AN ESSENTIAL INTRODUCTION

The first section provides non-technical people with the technical background necessary to understand the space and earth segments of the industry, culminating with the importance of the link budget. The concluding section of the course provides an overview of the business issues, including major operators, regulation and legal issues, and issues and trends affecting the industry.

What You Will Learn:

• How do commercial satellites fit into the telecommunications industry?

• How are satellites planned, built, launched, and operated?

• How do earth stations function?

• What is a link budget and why is it important?

• What legal and regulatory restrictions affect the industry?

• What are the issues and trends driving the industry?

The course is intended primarily for non-technical people who must understand the entire field of commercial satellite communications, and who must understand and communicate with engineers and other technical personnel. The secondary audience is technical personnel moving into the industry who need a quick and thorough overview of what is going on in the industry.

Concepts are explained at a basic level, minimizing the use of math, and providing real-world examples. Several calculations of important concepts such as link budgets are presented for illustrative purposes, but the details need not be understood in depth to gain an understanding of the concepts illustrated.

End of Primary Mission of NASA’s Spitzer Space Telescope

NASA’S SPITZER TELESCOPE WARMS UP TO NEW CAREER

WASHINGTON — The primary mission of NASA’s Spitzer Space Telescope is about to end after more than five and a half years of probing the cosmos with its keen infrared eye. Within about a week of May 12, the telescope is expected to run out of the liquid helium needed to chill some of its instruments to operating temperatures.

The end of the coolant will begin a new era for Spitzer. The telescope will start its “warm” mission with two channels of one instrument still working at full capacity. Some of the science explored by a warm Spitzer will be the same, and some will be entirely new.

“We like to think of Spitzer as being reborn,” said Robert Wilson, Spitzer project manager at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “Spitzer led an amazing life, performing above and beyond its call of duty. Its primary mission might be over, but it will tackle new scientific pursuits, and more breakthroughs are sure to come.”

Spitzer is the last of NASA’s Great Observatories, a suite of telescopes designed to see the visible and invisible colors of the universe. The suite also includes NASA’s Hubble and Chandra space telescopes. Spitzer has explored, with unprecedented sensitivity, the infrared side of the cosmos, where dark, dusty and distant objects hide.

For a telescope to detect infrared light — essentially heat — from cool cosmic objects, it must have very little heat of its own. During the past five years, liquid helium has run through Spitzer’s “veins,”
keeping its three instruments chilled to -456 degrees Fahrenheit
(-271 Celsius), or less than 3 degrees above absolute zero, the coldest temperature theoretically attainable. The cryogen was projected to last as little as two and a half years, but Spitzer’s efficient design and careful operations enabled it to last more than five and a half years.

Spitzer’s new “warm” temperature is still quite chilly at -404 degrees Fahrenheit (-242 Celsius), much colder than a winter day in Antarctica when temperatures sometimes reach -75 degrees Fahrenheit
(-59 Celsius). This temperature rise means two of Spitzer’s instruments — its longer wavelength multiband imaging photometer and its infrared spectrograph — will no longer be cold enough to detect cool objects in space.

What Effect Will Transformational Satellite (TSAT) Termination Have?

Defense Budget Recommendation Statement
As Prepared for Delivery by Secretary of Defense Robert M. Gates, Arlington, VA, Monday, April 06, 2009
DOD will “terminate the $26 billion Transformational Satellite (TSAT) program, and instead will purchase two more Advanced Extremely High Frequency (AEHF) satellites as alternatives.”

Transformational Communications Satellite (TSAT)
Advanced Wideband System
The Transformational Satellite System (TSAT) provides orbit-to-ground laser communications. Throughput for the five-satellite constellation could top out at 10 to 40 gigabytes per second, with a total program cost of $12 billion-to-$18-billion for the entire constellation.
The Transformational Satellite Communications (TSAT) System will provide DoD with high data rate Military Satellite Communications (MILSATCOM) and Internet-like services as defined in the Transformational Communications Architecture (TCA). TSAT is key to global net-centric operations. As the spaceborne element of the Global Information Grid (GIG), it will extend the GIG to users without terrestrial connections providing improved connectivity and data transfer capability, vastly improving satellite communications for the warfighter.
As the terrestrial aspects of communication in the TCA evolve, so will DoD satellite resources. The stated goal of the Transformational Satellite communications system is to provide improved, survivable, jam-resistant, worldwide, secure and general purpose communications as part of an independent but interoperable set of space-based systems that will support NASA, DoD and the IC. TSAT will ultimately replace the DoD’s current satellite system and supplement AEHF satellites.
The TCA proposes a radio frequency (RF), i.e., traditional radio-based, crosslink to complete the AEHF group of satellites or constellation. The constellation is called the Advanced Polar System (APS), which supports strategic and national users in the polar region. The APS is designed to withstand nuclear attacks and support the strategic mission with uninterrupted service. These satellites introduce the use of jam-resistant laser crosslinks for connection into the TSAT.
