Pseudorange is a term used in satellite-based positioning systems, such as Global Positioning System (GPS), to describe the calculated distance between the satellite and the receiver. It is called "pseudorange" because it is not an exact distance; rather, it is an estimate that accounts for several factors. The pseudorange is determined by measuring the time it takes for a signal to travel from the satellite to the receiver and then multiplying that time by the speed of light.
