TW2710/TW2712 兼容北斗、伽利略

The TW2710/TW2712 employ Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS G1, BeiDou B1, Galileo E1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It provides truly circular response over its entire bandwidth (49Mhz)thereby producing superior multipath signal rejection resulting in higher accuracy of position and timing.

The TW2712 has a pre-filter to provide extra protection against saturation by strong near frequency or harmonic signals, such as LTE.

TW2712具有预滤波,为强接近频率或谐波信号的干扰提供额外保护,如抗LTE移动通信信号。
