1. The accuracy of the phase center reaches the sub-millimeter level, and the phase center has high stability and good repeatability

2. Adopt 3D choke coil design to achieve excellent multi-path suppression effect

3. The antenna has high gain at low elevation angles, and has strong tracking ability to low elevation angle satellites,ensuring that the number of available satellites in the system is sufficient

4. The low noise amplifier has high gain, and the cable length can be more than 100 meters

5. Unique waterproof and dustproof design ensures that the core components are completely sealed and can work normally outdoors for many years
