TW3740/TW3742 高精度定位、授时,严格任务,兼容北斗、伽利略40dB

The TW3740/TW3742 employs Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS G1, BeiDou B1, Galileo E1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1559 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and time.
