u-Blox ZED-F9 RTK L1/L2 GPS
The 3DR ZED-F9 GPS is a high-performance device capable of using all constellations simultaneously, including the more precise L2 band, making it the most precise GPS available today.
ZED-F9 GPS from 3DR also features a sophisticated proprietary RF stage, which delivers high gain and high noise immunity compared to passive antennas. It also uses less space and weight than most active antenna counterparts and eliminates signal loss caused by u.Fl/SMA antenna connectors and long cables.
