GA370 GNSS Antenna

GeoRTK Navigation Limited

GNSS Antenna GA370
● Support GPS L1/L2,GLONASS L1/L2, BDS B1/B2/B3 frequencies.
● Multi-path rejection board inside can eliminate the multi-path influence to measurement error.
● Adopt multi feed design to ensure the superposition of phase center and geometrical center, and minimize the influence to measurement error.
● Water & dust-proof design ensures absolute seal of kernel parts, capable for long time outdoor operation.
●  Very low noise figure.
●  Lightning proof circuit inside can protect the LNA from being damaged by surge immunity.
