Inside Frequency Control

The U.S Department of Homeland Security considers 13 of the nation’s 16 critical infrastructure sectors to be ‘critically dependent’ on PNT technology. Also, a loss of PNT would cost the U.S an estimated $10 BILLION a day. Not only do many everyday consumers use PNT & GPS on a daily basis, it's also crucial for military and intelligence operations. Other industries that strongly rely on GPS based PNT include

• Radio communications
• Network synchronization
• Intelligence systems
• Information gathering
• Cruise missiles
• Weapons systems
• Electronic warfare

A Modular Open Systems Approach (MOSA) is becoming critical in Department of Defense (DoD) systems. If you're unfamiliar with this critical system design approach (or need a little brush-up) you're in the right place (and should totally keep on reading to discover the 5 core principles).

But first, a few quick basics. MOSA is a business and technical strategy for easily developing new defense systems or modernizing existing ones. This will help the Department of Defense provide joint combat capabilities required for 21st century warfare.

MOSA also provides the ability to support and evolve these 21st century capabilities over their total life-cycle.

Raytheon's Next Generation Jammer (NGJ) has been under development now since 2013. In 2016 the US Navy awarded the company a 1 billion dollar engineering and manufacturing development contract for the NGJ system slated to replace the ALQ-99 legacy systems used in the EA-18G electronic attack aircraft.

There is an old pearl of wisdom which claims that necessity is the mother of invention and nowhere is that truer than in the history of warfare, and especially electronic warfare. New military technology is always followed by innovative countermeasures developed specifically to defend against the new threat. In the case of electronic warfare, defensive measures quickly evolved into new offensive and intelligence gathering technologies.

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.
