Universal Measuring Antenna
Place of Origin： China
Universal Measuring Antenna is a four-system full-band antenna covering BDS, GPS, GLONASS, and GALILIE. The antenna adopts a multi-feed design, is equipped with an anti-multipath choke plate, and uses a waterproof and UV-proof cover. The specific phase center is stable, positioning accuracy is high, and low elevation angle signal reception is good. Has passed the US NGS certification test.
- Features
- Parameters
1. The multi-feed point design scheme is adopted to realize the coincidence of the phase center and the geometric center and minimize the influence of the antenna on the measurement error
2. The antenna unit has high gain and beam width in the pattern to ensure the technical effect of low-elevation signals, and it can still receive the satellites normally in some severely obstructed occasions
3. Equipped with anti-multipath choke plate to limit the influence of multipath on measurement accuracy
4. Waterproof and UV-proof outer cover, which provides protection for the antenna to work in the field for a long time
