GPS-18380

R High precision Professional GNSS wireless solutions provider GNSS Antenna Model：TOP106 High-precision GNSS Antenna STOTON TOPGNSS TOP106 four-system 7-band measurement antenna can simultaneously support GNSS multi-frequency signals: GPS L1, L2 and Beidou B1, B2, B3 / GLONASS L1 L2 frequency band signals. The multi-feed antenna design ensures the coincidence of the antenna phase center and the geometric center and improves the measurement accuracy. Built-in low-noise amplifier module, pre-stage and multi-stage filters can filter out interference signals to ensure normal operation in harsh electromagnetic environments. The radome is made of high-temperature-resistant PC material. The plastic adopts a streamlined design and is widely used in geodetic surveying, bridge construction, ocean surveying, underwater topographic surveying, unmanned aerial vehicles, unmanned vehicles, unmanned ships and other high-precision positioning and navigation timeout fields. 1.Antenna characteristics 频率范围 1555~1615MHz /1198~1278MHz （Frequency Range） 端口阻抗（port Impedance） 50 Ohm 极化方式 (Polarization) 右旋圆极化 (RHCP) 天线轴比 (Axial Ratio) ≤3dB 水平面覆盖角度 (Elevation Coverage) 360° 电压驻波比 ≤2 (VSWR) 天线单元增益 （Gain of Antenna) ≥5dBi 相位中心误差 （Phase Center Error) ±2mm 低噪放增益 40±2dB 噪声系数 (LNA Gain) ≤1.5dB （Noise Figure） 输出驻波 (VSWR) ≤1.5 输入驻波 （VSWR） ≤1.5 增益平坦度 (Gain Flatness) ±1dB 输出P1dB压缩点（Pout at 1dB Gain Compression Point) ≥0dBm 工作电压 (LNA Drain Voltage) 3.3-12VDC 工作电流 (LNA Current Consumption) ≤45mA 差分传输延迟（delay）差分传输延迟（delay）
