What type of navigation does LORAN-C provide?

LORAN-C, which stands for Long Range Navigation version C, provides precise navigation capabilities. It accomplishes this by using ground-based radio transmitters that broadcast signals at low frequency. These signals are received by LORAN-C receivers on boats or ships, which then calculate the user's position based on the time it takes for the signals to travel from multiple transmitters to the receiver.

The key aspect of LORAN-C's function is its ability to determine the user's location with a high degree of accuracy, typically within a range of 0.25 nautical miles under ideal conditions. This precision is essential for navigation in various maritime operations, including fleet movements, search and rescue missions, and ensuring safe passage through busy or shallow areas.

In the context of the other navigation types mentioned, global navigation refers to systems that can provide worldwide positional data, like GPS, while local navigation refers to navigation that occurs within a limited area, typically using landmarks or shorter-range methods. Relative navigation generally involves determining a position relative to another known point, which can also lead to less precision compared to LORAN-C. Thus, the ability of LORAN-C to deliver precise location information is what makes it the correct choice in this question.
