Trimble GNSS Smart Antennas are the simple solution to all your site measurement and stakeout applications. These high-accuracy smart antennas track positioning information from GPS, GLONASS and Galileo satellite constellations. They use satellite signals to compute exact locations and give contractors an easy-to-use, wide area measurement system for a variety of site preparation and grade checking applications. Trimble GNSS Smart Antennas can be used as either a rover for site measurement and stakeout, or as a base station for site measurement and machine control operations. And because the GNSS receiver, GNSS antenna, radio and battery are integrated into one housing, you donít have to deal with cables and multiple components.
