This paper deals with the application of wireless transmission technology to longterm monitoring GPS (Global Positioning System) receivers. They consist of five parts: antenna, receiver, user client computer, interface and power supply. The antenna is mounted on the structure to be monitored and is connected with the receiver by a coaxial-cable through which the radio frequency signals are transmited. The receiver unit acquires, tracks and demodulates the satellite signals and provides, through an interface made wireless, the resulting GPS raw data to the user client computer for being futher processed by a suitable positioning algorithm. The power supply reaches the computer by a wired link, while the other modules rely on batteries.
