The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure to ensure that the phase center and the geometric center coincide and reduce the impact of the antenna on survey errors.
Special structural design is adopted to achieve excellent multi-path rejection effect, high phase center stability and good repeatability.
The low-noise amplifier part adopts a pre-filtering scheme, which filters the received signal first and then amplifies it, which can effectively reject out-of-band strong jamming signals, avoid amplifier saturation, and improve system reliability.
The antenna has a high cross-polarization ratio and strong resistance to multipath jam.
Built-in lightning protection circuit effectively protects the amplifier and ensures normal operation in harsh outdoor environments.
Built-in voltage stabilizing circuit can operate normally within a wide input voltage range.
The unique waterproof and dustproof design, meets IP67 waterproof level, ensuring that the core unit and components are completely sealed to meet the complex outdoor environment and can work normally outdoors for many years.
