Choosing a GPS Receiver

When choosing a GPS receiver, it's important to understand the differences between different products on the market. Most GPS receivers are designed to receive signals from the United States GPS network. However, Russia has its own GPS network too. Some newer GPS receivers are designed to pick up signals from both the US and Russian system. In many cases, receivers that are designed to pick up signals from both these systems can lock on to one's destination faster. In addition, they often offer better reception in city environments with tall buildings and other obstructions. In some cases, dual-purpose GPS receivers can lock on to an individual's location while he or she is in a subway or building.
