You must have used a GPS receiver. It is easy to be found in most places, such as smartphones, cars, and computers. They are used to track your location all over the globe.
GPS Receiver for Arduino is a unit embedding GPS module and antenna in a small foot-print enclosure. By using the TinyGPS library, Arduino can retrieve geographic coordinates (latitude and longitude, altitude), speed, heading, and GMT time.
The update rate is an important performance index of a GPS receiver. Most GPS in mobile phones provide an update rate of 1Hz, which means, only one set of data can be retrieved in one second. For GPS receivers with 1~10Hz, the data interval is much reduced and thus can be used for more demanding applications (e.g. on fast-moving vehicles).
