Sometimes being on time isn鈥檛 just the right thing to do, it鈥檚 the only thing to do. That鈥檚 especially true if your job is protecting our country or operating the financial, telecom, and energy industries, which rely on PNT鈥擯osition, Navigation, and Timing鈥攖echnology delivered through the Global Positioning System, or GPS.

Thirteen of the 16 most critical categories of the U.S. infrastructure rely on GPS for position or timing information, according to the Department of Homeland Security. Missile defense is another vital user of timing information. It requires precision timing and frequency signals that are accurate and robust even when GPS is not available.

That鈥檚 why the Missile Defense Agency (MDA) asked 无忧传媒 to find new ways to protect the timing information essential to finding and tracking ballistic missiles鈥攁nd the missiles that shoot them down.

One way to share timing information is through traditional landlines, but you can鈥檛 run a wire between all the systems that protect our country. So, when scientists looked at the sky, they saw an affordable and easy way to do it with GPS. However, a system was needed to be certain that time would be available when GPS is disrupted.

MDA found the needed expertise. We were tasked with designing accuracy, stability, anti-jam, anti-spoof, and redundancy capabilities to meet the demanding requirements of missile defense.

We鈥檙e not equipment manufacturers and we don鈥檛 build GPS or back-up clocks. We take an unbiased approach that focuses on systems integration to create solutions based on standards and best practices.

It鈥檚 not easy to hire a PNT engineer, however, because schools don鈥檛 offer degrees in PNT. At 无忧传媒, we hire smart engineers and let them learn from experienced senior PNT engineers in our PNT lab.

We鈥檝e invested in GPS simulators, instrumentation, and robotic mobility platforms to give engineers the tools to experiment with techniques to mitigate problems before they鈥檙e discovered in the field.
