gps receiver


a device that is capable of receiving information from GPS satellites and then to calculate the device’s geographical position. Using suitable software, the device may display the position on a map, and it may offer directions. GPS receivers are the most important hardware in a GPS surveying operation. Their characteristics and capabilities influence the techniques available to the user throughout the work. There are many different GPS receivers on the market. Some of them are appropriate for surveying,
