This is a 3V active GPS glonass antenna intended for use with the GPSDO kit used with the USRP N200/N210 Series. The antenna can also be used for the USRP E310, which has an integrated GPS(SMA to SMB adapter needed).  A GPSDO locked to the GPS constellation can provide time synchronization within 50 ns of the global GPS standard and very high clock accuracy.
Faster GPS signals capture, lower power consumption, stronger anti- performance and wider working voltage range.
Magnetic base allows you to conveniently attach it to any metal surface.
No power adapter needed: powered by the head unit.
Recording your driving track, speed and longitude and latitude data. All of these data can be seen in designated player.
