Product overview
The SYN2307 GNSS timing module is an ultra-low power super high sensitivity ultra small receiving module developed by Xi'an synchronous Electronic Technology Co., Ltd., which supports GPS, GLONASS, BeiDou, Galileo 4 navigation systems, and supports SBAS, QZSS and other auxiliary DGPS satellites.The product is built in LNA+SAW+FLASH, compatible with the mainstream timing location module, and adopts advanced multi-path suppression technology to support single Beidou, single GPS, GPS+ Beidou or GPS+GLONASS mixed time service mode.
The timing module has the characteristics of high time accuracy, small size, stability, reliability and easy integration. It also uses SMD surface mount package to facilitate mass production of satellite timing equipment, especially for power, telecommunications, finance, broadcasting and other precision time service areas.
Key word: Time service module, Beidou timing module, dual mode timing.
