High precision measurement of GNSS antenna
Support: GPS / GLONASS / BEI DOU three satellite system.
Features:
Integrated BD B1 & B2 & B3 and GPS L1 & L2 and GLONASS G1 & G2 3 system seven-band measurement antenna, can be widely used in geodesy, bridge construction, marine survey, underwater terrain measurement and other occasions. The antenna uses multi-feed point design to ensure that the antenna phase center and geometric center coincidence, improve the accuracy of measurement. Built-in low-noise amplifier module, the use of pre-and multi-stage filter filter interference signal to ensure that the normal work in harsh electromagnetic environment. Small size, light weight.
