GNSS Antenna GGA7601 GGA7601 adopted unique wideband antenna technology design provides superior low elevation satellite tracking, multipath reduction and sub-millimeter phase center stability. The new low noise amplifier (LNA) is used to provide exceptional low measurement noise for superior measurement quality with excellent out of band rejection. The new LNA technology also has high gain which ensures the operation with long cable (100 meters +). ● Support GPS L1/L2、GLONASS L1/L2 and BDS B1/B2/B3 bands. ● Ideal for fixed reference stations and GNSS infrastructure networks. ● Water & dust-proof design ensures absolute seal of kernel parts, capable for long time outdoor operation. ● Sub-millimeter phase center repeatability, antenna gain has been optimized to allow use with most manufacturers geodetic receivers. ● LNA has high gain which ensures the operation with long cable (100 meters +). |
