New navigation technology helps F-22 sharpen angles of attack

The success of high-speed air-to-air combat engagement accelerated flight into enemy fire against air-defenses, aerial surveillance missions, and precision-strikes on enemy ground targets of course rest upon a pilot’s ability to know a plane’s exact location, movement patterns and angle of attack.

This kind of combat operation is often heavily interwoven with, or even reliant upon, “secured” navigational systems such as GPS and Inertial navigational technologies. GPS, while ubiquitous and critical to military operations, is also known to in some cases be vulnerable to hacking, jamming and various kinds of enemy intrusion. The risk of having combat maneuvers and tactics compromised is therefore significant, a circumstance that continues to inspire widespread Pentagon efforts to both “harden” GPS and establish supplemental and alternative guidance systems.

An emerging, shoe-box size navigation capability is being developed to address these challenges and vastly improve and strengthen what’s known as positioning, navigation and timing (PNT)

Hello, this is Bien Perez from the South China Morning Post’s Technology desk, with a wrap of our leading stories this week.

Amid rising tensions with Washington, Beijing has had to downplay some of the country’s technological catch-up efforts, such as the “Made in China 2025” policy road map. Sensing a threat to US global hi-tech dominance, the Trump administration had seized on the plan as an example of what it sees as unfair state intervention in China’s economy.

In reality, however, China’s pace of hi-tech initiatives has not slowed down. The country’s spending on research and development broke a record last year, reaching 2.2 trillion yuan (US$324 billion), according to data released in August by three Chinese government agencies, covering the private and public sectors. That
