Feature:
1.External multi-satellite and multi-frequency GNSS measurement antenna, which supports the reception of satellite navigation signals of Beidou II, GPS, GLONASS and GALILEO , meets the requirements of compatibility and high precision measurement at present, and can be widely used in geodetic survey, ocean survey, precision agriculture, deformation monitoring and other high precision navigation and positioning occasions.
2.The antenna is designed with single-layer multi-feed ultra-wideband (UWB) to minimize the elevation difference of phase center in the whole working frequency band.
3.The antenna unit has high gain and small gain roll-off, which can receive satellite signal at low elevation, and ensure that the satellite can receive the satellite normally in some severe occlusion situations.
4.Low Noise (LNA) uses multi-stage filtering technology to effectively suppress out-of-band interference signals and improve the reliability of the .
5.Parasitic network diameter suppression technology can effectively reduce the of multipath signal on measurement accuracy.
The waterproof and anti-ultraviolet coat provides a guarantee for the long-term field work of the antenna.
