8-Channel Satellite Antenna

B1/L1/E1 CRPA 8-Channel High-Precision Positioning

ZD-KXAT170_8B1L1E1
This CRPA Protected Satellite Antenna is engineered for high-precision positioning in complex electromagnetic environments, supporting BDS_B1, GPS_L1 and GAL_E1 multi-system signal reception with an 8-channel antenna array. It features professional RF signal processing with 7-direction electromagnetic interference protection: ≥110dB single-direction, ≥100dB three-direction and ≥85dB seven-direction (reference signal -130dBm). Equipped with optional high-efficiency positioning functions, it achieves cold start ≤60s, hot start ≤10s and lost lock reacquisition ≤2s, with positioning accuracy ≤10m and speed accuracy ≤0.2m/s. Built with SMA-KF RF interface and J30J-9ZKP power interface, it supports 12V-32V wide voltage input with power consumption ≤20W. Boasting high reliability (MTBF ≥5000h, 24h continuous operation) and IP65 waterproof rating, it adapts to harsh working conditions (-45℃~+70℃) and storage environments (-50℃~+75℃). The magnesium alloy body (≤900g) with compact dimensions (Φ165±0.5mm×H63±0.5mm) ensures easy integration for various industrial and airborne positioning scenarios.
