Which systems receive information from the GPS?

The selection of the correct option revolves around understanding the systems that typically leverage GPS data for their operations. The Terrain Awareness and Warning System (TAWS) is designed to enhance safety by providing alerts about terrain proximity, which depends on accurate positional data from GPS. The Inertial Reference System (IRS) uses GPS to refine its position and orientation calculations, thus improving the accuracy of navigation. Weather radar systems (WX radar) can also utilize GPS data to position themselves accurately, ensuring that any weather-related information is referenced correctly as the aircraft moves.

Therefore, the combination of TAWS, IRS, and WX radar collectively illustrates a cohesive suite of systems where GPS information plays a critical role in operating effectively. This ensures that navigation, situational awareness, and safety measures are all backed by precise and reliable positional information.
