CHOKE RING ANTENNA APPLICATION FIELD
As the most important applications on safety, GNSS gives the significant changes on the way of implementing the deformation monitoring. With multi-path suppression technology, 3D choke ring antenna can effectively eliminate signal transmission errors. It also has anti-interference performance, which can suppress useless electromagnetic signals and prevent the receiver from being blocked by power grids, communication base stations and radio stations. Choke ring antenna features low elevation angle, high gain, good signal reception and stable phase center, which ensures sub-millimeter positioning accuracy. At present, choke ring antennas are widely used in the field of high-precision surveying and mapping, including scenes of geodesy, road construction, marine survey, channel survey, earthquake monitoring, landslide monitoring, bridge deformation monitoring, etc.
