Description
The precision antenna adopts a multi-feed
point design scheme, and the phase center stability is high. It can receive GNSS L,L2,
GPS, GLONASS, BDS, and GALILEO four major GNSS system satellite signals, while
supporting L-Band satellite-based differential signals. The antenna structure
adopts double waterproof and anti-ultraviolet shell design, which is widely
used in intelligent driving, surveying and mapping, driving test driving
training, precision agriculture, digital mechanical operation and other fields.
Features
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 occluded occasions
3. With anti-multipath choke plate,
effectively reduce the impact of multipath on measurement accuracy
4. Waterproof and anti-ultraviolet cover,
to provide protection for the antenna to work in the field for a long time
