LOCOSYS HAWK R1 & R2 RTK GNSS

HAWK R1 and R2 (with compass) is a L1+L5 dual-frequency RTK centimeter-level GNSS receiver designed for UAV applications. The receiver is capable of concurrently tracking global civil navigation systems, including GPS, GLONASS, GALILEO, BEIDOU and QZSS. It acquires both L1 and L5 signals at a time while providing the centimeter-level RTK positioning accuracy.
