Google Earth is a virtual globe, map, and geographical information program where you can virtually fly anywhere on earth. You can view images, maps, terrain, and 3D images of any place across the globe. Now, you can use Google Earth into a GPS Navigation tool for your laptop or net book with GPS for Google Earth.
GPS for Google Earth is an application that allows users to view real-time images in Google Earth even without opening a Web browser. This application only requires a small part on your screen for you to see the map for your current position on Google Earth. What is cool about this is that you can see even your current movement. It supports clear images at night and even with fog or mist.
Another great thing is that GPS for Google Earth only requires a GPS receiver. You can only use a GPS mouse or a GPS USB dongle, if you have any.
