The unmanned aircraft system (UAS) Part two: The electronics inside

-September 23, 2013

In Part one of this article, we introduced the UAS, in particular, the Northrop Grumman Global Hawk. In this part two we will take a look inside the aircraft to see what makes it one of the world’s most advanced UAS we have ever seen.

The AN/ZPY-2 Multi-Platform Radar Technology Insertion Program (MP-RTIP)

This radar system uses an active electronically scanned array (AESA) technology as well as COTS hardware that creates a long-range, extremely high-resolution synthetic aperture radar (SAR), ground moving target indicator (GMTI) and air target tracking capabilities.

The MP-RTIP sensor consists of three architectural elements. These elements are the antenna, the radio frequency electronics, and the signal processor. The architectural elements allow for common interface definitions across the various host platforms.

The MP-RTIP software can function independently of the physical location of the hardware that it is controlling. The software architecture is also host platform independent to the maximum extent possible.
