TOP901 GNSS antenna adopts multi arm and multi feed technology, supports L1, L2 / L5 and L-band satellite navigation signal reception of Beidou II, GPS, GLONASS and Galileo systems. It has built-in multi-level filters and low noise amplifiers. It has good out of band suppression and strong anti-interference ability, ensuring normal operation in a bad electromagnetic environment. Meet the requirements of GNSS multi system compatibility and professional level high-precision measurement.
-
Multi arm spiral technology is adopted to ensure the right-handed circular polarization and phase center performance and reduce the influence of measurement error;
-
The antenna unit has the characteristics of high gain and small gain roll off, and has good reception effect for low elevation satellite signals;
-
Ingenious low noise, high gain amplification and excellent out of band suppression;
-
Small size, light weight, easy to carry and install.
it is suitable for occasions requiring volume and weight, such as UAV, micro RTK, sub meter handheld / tablet and other portable devices.
