Product
GPS500 Small Measurement Antenna
Place of Origin： China
High-precision antenna adopts a multi-feed point design scheme with high phase center stability. It can receive GPS, GLONASS, BDS, GALILEO satellite signals of the four GNSS systems, and support L-Band satellite-based differential signals. The antenna structure adopts double waterproof and UV-proof shell design. The product has passed the authoritative test of NGS in the United States. It is now widely used in intelligent driving, surveying and mapping, driving test and driving training, precision agriculture, digital mechanical operation and other fields.

- Parameters
- Application
1. The antenna part adopts a multi-feed point design scheme 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 reception of low-elevation signals, and it can still receive satellites normally in some severely obstructed occasions
3. With anti-multipath choke plate, effectively reduce the impact 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
