Inside Frequency Control

The introduction of reliable, long-range radar systems during World War II represented a fundamental change in the nature of warfare. For the first time, it was possible for friendly forces to see the enemy from a distance without being detected— an incredible advantage. Naturally, the emergence of a new technological innovation motivated other parties to find ways to counter it, leading to the development of radar jamming and other deception technologies.

In this article, we will discuss jamming and deception in detail, and how innovations like the Next Generation Jammer are shaping the next chapter in the electronic warfare arms race.

When radar was first used in combat, it represented what is known as a “Revolution in Military Affairs” (RMA), a term used to describe a tactical, doctrinal, strategic, or in this case, technological change in military theory and activity that fundamentally changes the nature of warfare. World War II saw the first widespread use of radar on both sides of a conflict, and led to the emergence of electronic warfare as a method of counteracting the other side’s radar abilities while defending the friendly use of the electromagnetic spectrum. This competition spawned the evolution of many different radar functions for specialized applications. This article will explore various types of radar systems that exist and the functions they serve.

In Part 1 of our series on COTS components for space applications, we discussed why the government is increasingly turning to “commercial off the shelf” parts for spacecraft, satellites and more. COTS parts have already been successfully adopted in many military applications, but when it comes to space, COTS adoption has been much slower.

Space exploration has never been cheap. In the days of the Apollo program, the cost of sending payloads into space was such that only government agencies with billions of dollars to spend could afford it. Over time, those costs have begun to come down, but even with advances in launch technology, funding for such activities ebbs and flows. In the wake of budget cuts for military and aerospace Research and Development, there has been much pressure to develop systems and designs that meet the needs of space projects and reduce costs without sacrificing quality. This is where COTS (Commercial Off-The Shelf) products offer a potential solution.

Bliley Technologies has been recognized in the frequency control industry as one of the premier suppliers for high quality OCXOs for over 85 Years.  Bliley has been moving up the value chain from an RF system perspective.  Within the last year, Bliley has developed a commercial LEO solution to provide a master reference oscillator which provides the functionality of a PLL and OCXO from the GPSDO design and is currently in production. 

Small satellites have grown dramatically over the past decade... and they are still growing fast and furiously. In this post, you'll learn about how to achieve mission success for satellites and how GPS Disciplined Oscillators (GPSDOs) can do the trick. 

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.”

Podcasts have never been more popular. Whether you are commuting, in the gym or just relaxing at home, they’re a fantastic way to stay on top of personal interests as well as developments in your industry. For engineers and project managers working in the RF industry, some of the biggest growth is expected to occur in the field electronic warfare, which is slated to become a nearly $20 billion industry by 2026. To help you gain a sense of where the electronic warfare industry and the defense sector as a whole are headed in the near and long-term, we’ve compiled a list of some of the best podcasts relating to these topics.
