What's the Difference Between DVB-S2 and DVB-S2X Standards?

Posted by Rob Rutkowski on Jun 26, 2018 8:32:00 AM

In 1994, the world's first digital satellite TV services were launched in Thailand and South Africa. They utilized the newly developed Digital Video Broadcasting Satellite (DVB-S) system.

Over time, DVB-S became the most popular system for delivering digital TV broadcasts. Technology has advanced and spread tremendously since then, which lead to an increased need for advances to the DVB-S system. Thus, the DVB-S2 and DVB-S2X systems were born!

Let's take a look at both DVB-S2 and DVB-S2X and the main differences between them.

Communication With Aliens - Interstellar Messages in Deep Space

Posted by Rob Rutkowski on Jun 5, 2018 7:50:00 AM

We can't possibly be the only intelligent life-forms in this infinite universe, can we? I mean, there's still plenty of exploring to do in our own solar system let alone nearby stars, our entire galaxy, and surrounding galaxies. Will our current deep space communication efforts, like Voyager 1, ever stumble across alien life so us humans can say, "Hi! We're here!"? Or will it take so long that our messages would be more like, "Hi! We were here!"? 

Let's explore some current communication efforts to make contact with aliens and how they work.

Laser Communication in Space Could Multiply Data Rates by 100x

Posted by Rob Rutkowski on May 15, 2018 8:06:00 AM

Since the beginning of NASA, radio communication has been the go-to method of communication for spacecrafts. Well, that's about to change. NASA has recently announced they will be making a major change to some of their upcoming communication systems by implementing new, cutting-edge, laser communication technology.

The Innovative History of HRL Laboratories

Posted by Bliley Technologies on Mar 13, 2018 6:30:00 AM

To say that HRL Laboratories has made significant contributions to cutting-edge science and technology would be quite an understatement. Known today by its legal corporate title HRL Laboratories LLC, the storied company traces its roots back to the legendary Howard Hughes. Hughes set the standard for HRL's innovative mission, advising his contemporaries to "Do the impossible. Because almost everyone has told me my ideas are merely fantasy."

VSAT Terminals: What Are They and How Do They Work?

Posted by Bliley Technologies on Dec 12, 2017 6:30:00 AM

Satellite communication touches our lives in ways most people don’t fully appreciate. From GPS to satellite TV to the communication networks that make modern economic, military and political affairs possible, there are few areas of life that the rise of SATCOM technology has not shaped in some way, directly or indirectly. While visions of massive arrays and constellations might be the first thing that comes to mind when some people think of satellites, today we’re going to focus on something a little less visually impressive but just as important; the Very Small Aperture Terminal, or “VSAT.”

The Impact of RF Engineers on the Commercial Space Industry

Posted by Bliley Technologies on Nov 28, 2017 6:30:00 AM

 

While the expansion of the private sector into space is still in its infancy, there is little doubt that it will prove to be one of the most significant economic developments of this century, and RF engineers are one group of industry specialists that are making it happen. Indeed, it's almost impossible to overstate the impact that engineers specializing in radio frequency tech have had and will continue to have, not only with operating and maintaining commercial space activity but shaping it as well. Let’s explore all the different ways that RF engineers are making the “Space 2.0” era possible.

Why Satellite Ground Stations Are So Important to Mission Success

Posted by Bliley Technologies on Nov 21, 2017 6:30:00 AM

So much of the focus in SATCOM technology pertains to what goes on in outer space, but what happens down here on earth is just as important. The fact is that every satellite, no matter how advanced, is still only a part of a larger system. Today, you'll learn the important role that satellite ground stations play in making SATCOM possible, and some of the challenges (and possible solutions) for organizations working with LEO satellites on the ground.

How to Enhance a High Throughput Satellite (HTS) Using Beam Hopping

Posted by Bliley Technologies on Nov 7, 2017 6:30:00 AM

The average person probably doesn’t spend any time thinking about satellites unless he or she is specifically entering an address into a GPS device— and even that would be a stretch. Satellite communication has become such a pervasive, omnipresent influence in our lives, our economy, and our government that we simply take it for granted. With the advent of high-throughput satellites (HTS), this trend has only increased. Speeds and data capacities never before dreamed of are becoming commonplace, and dramatically improving SATCOM capabilities in both the public and private sectors. A core technological attribute that is enabling the HTS revolution is a technique called beam hopping.

Spot Beams vs. Wide Beams for Satellite Communications

Posted by Bliley Technologies on Oct 31, 2017 6:30:00 AM

Satellite communications make it possible for so much of today's technology to function. From GPS and HDTV, to the safety and protection our armed forces provide, there are many uses for satellites. However, different uses require different techniques for transmitting the data back to earth in the most effective way.
