Antennas and accessories

The GPS520 is a four-system full-band external measurement antenna covering GPS, GLONASS, BDS, and GALILEO, meeting the current requirements for multi-system compatibility in measurementequipment. It can be widely used in geodetic surveying, marine surveying, waterway surveying, dredging surveying, earthquake monitoring, bridge deformation monitoring, landslide monitoring, port container operations, smart agriculture, driver's license testing and training, and other applications.

The antenna elements feature high gain and wide beamwidth, ensuring strong signal reception even at low elevation angles. This guarantees rapid satellite lock-on and stable GNSS navigation signal output even in complex environments with obstructions.

● Stable phase center ensures millimeter-level positioning accuracy.

preventing the receiver from being interfered with by other wireless communication systems, and effectively reducing the risk of system loss of lock-on, such as electromagnetic wave interference from power grids, communication base stations, radio stations, etc.

The antenna section adopts a multi-feed design to achieve the coincidence of the phase center and the geometric center, minimizing the antenna's impact on measurement errors.
