A GPS (Global Positioning System) receiver will help show where you are and if loaded with you route it can give an indication of where to go. Again make sure you know how to use it and have a backup method of navigation - In some places, deep valleys or forests a GPS receiver may not work correctly.
An alternative to the American GPS system is the Russian GLONASS system. There are not as many suitable receivers available but there are a few that use both GPS and GLONASS.
The European satellite-navigation system, Galileo should be available in 2010 and is designed to have higher availability and accuracy. As an interim measure, the European Geostationary Navigation Overlay Service (EGNOS) system in Europe, or WAAS in America, or MSAS in Japan, can help some GPS receivers provide more accurate positions.
