581The ZKAT-GGB790 Airborne Measurement Antenna is a full-band active aviation antenna. The antenna features a double-layer multi-feed design that supports the navigation signals of BDS, GPS, GLONASS, and Galileo satellite systems. With its compatibility with multiple satellite systems, the antenna meets the requirements of airborne high-precision measurement applications.
Feature:
1) The antenna features a high phase center stability, with the phase center aligning perfectly with the geometric center. The accuracy of the phase center is 1mm, which effectively suppresses multipath interference.
2) By adopting a pre-filter and multiple-stage filtering scheme, the antenna can effectively suppress strong interference signals outside the band.
3) The antenna is an integrated voltage regulation circuit, allowing it to operate normally across a wide input voltage range.
4) The antenna features a compact, lightweight, and low-drag shape, making it suitable for installation on the aircrafts skin.
5) The antenna can operate normally in harsh high-altitude conditions, such as low temperatures, low air pressure, vibration, and impact, etc.
