With the advent of the smart phone, just about everyone now has access to a high quality GPS receiver. There are a wide variety of GPS apps available to view and use that information, from Google Maps to specialized apps for hikers and boaters. GPS Test is an example of a simple, free app that can be used to determine your place on the earth – latitude, longitude and altitude – and to show how GPS works. Who knew there were that many GPS satellites overhead.
