What does Pseudo Range indicate in GPS?

Pseudo Range in GPS systems represents the time it takes for a signal to travel from the satellite to the receiver, plus any errors that may occur in the process. This time lapse is crucial because GPS relies on timing to calculate the distance from the satellite to the receiver. When the GPS receiver picks up signals from multiple satellites, it measures the pseudo range for each one, allowing it to triangulate its position based on the time it took for those signals to reach it.

The pseudo range is not an exact measurement of distance; instead, it accounts for the time of flight of the signal modified by potential errors due to satellite clock discrepancies, atmospheric conditions, and other factors. This means that when a GPS receiver analyzes the pseudo range, it uses that information to refine its positioning calculations accurately. Thus, option B accurately identifies the essence of what pseudo range indicates in the GPS system.
