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.
Note
HAWK R1 and R2 GNSS requires L1 and L5 RTCM GNSS correction data for a stable RTK fix
Key Features¶
Concurrent reception of L1 and L5 band signals
Centimeter-level RTK high position accuracy
Support GPS, GLONASS, BEIDOU, GALILEO, QZSS
Capable of SBAS (WAAS, EGNOS, MSAS, GAGAN)
Support 135-channel GNSS
Fast TTFF at low signal level
Free hybrid ephemeris prediction to achieve faster cold start
Default 5Hz, up to 10 Hz update rate, SBAS support 5Hz only
