Which characteristic is typically associated with satellites used in navigation?

The characteristic that is typically associated with satellites used in navigation is that they send data to triangulate locations. Navigation satellites, such as those in the Global Positioning System (GPS), transmit signals that provide precise timing and positional information to receivers on the ground. When a receiver captures signals from multiple satellites, it can determine its exact location through a process known as triangulation or trilateration. By analyzing the time it takes for the signals to reach the receiver, the system can calculate distances from each satellite and pinpoint the user's position accurately.

In contrast, options involving audio signals or powerful light signals are not typical for navigation satellites. Navigation systems rely on radio signals rather than audio for communication. Additionally, while navigation satellites do coordinate with terrestrial navigation systems for accuracy and reliability, the primary function of navigation satellites is to provide location data through signal transmission, making the correct answer focused on data transmission for triangulation.
