8 channels GNSS protect antenna

ZD-KXAT150D_8B1L1E1G1 is a GNSS protect antenna launched by ZDTECH, which integrats antenna array, RF module and processing module as core components. It supports receiving, amplifying, downconverting, filtering and processing signals of 8 frequency bands across 4 systems including BDS B1, GPS L1, GALILEO E1 and GLONASS G1, with 7-direction electromagnetic signal protection capability. The signal processing performance of single/three/seven directions reaches ≥110dB, ≥100dB and ≥90dB@-130dBm respectively. The antenna is optional with high-precision positioning function, featuring cold start <60s, hot start ≤10s, fast lost lock reacquisition and positioning accuracy ≤10m, and also has optional capability.

Adopting 12-32V wide voltage power supply, its power consumption at room temperature is less than 20W. It is equipped with SMA-KF airborne RF interface and J30J-9ZKP power interface, with sea gray appearance, diameter of 165±0.5mm, height of 63±0.5mm and weight ≤700g. With MTBF ≥2000 hours and continuous working time ≥24 hours, its operating temperature and humidity range is -45℃~+70℃/10%~90%RH, and storage range is -50℃~+75℃/10%~95%RH, adapting to complex and harsh operating environments. It greatly improves the working stability of positioning devices under complex electromagnetic conditions, making it an ideal choice for various high-precision positioning scenarios.
