Technical features
1. The antenna part adopts a multi-infeed design and a completely symmetrical antenna structure to realize the coincidence of the phase center and the geometric center, and reduce the influence of the antenna on the measurement error;
2. Antenna gain is high, beamwidth is wide, and noise figure is low, ensuring good satellite signals are received;
3. The LNA part adopts a prefilter design, which effectively suppresses out-of-band strong interference signals, avoids amplifier saturation, and improves system reliability.
4. The shell is made of high temperature resistant and highly reliable plastic materials to ensure normal use under high altitude and high speed conditions;
5. the overall waterproof design, waterproof level reached IP67 .
