SIMCom presents a high performance GNSS module accompany with GNSS antenna-SIM33EAU. This is a standalone GNSS module include an embedded patch antenna on it. Designed with MTK’s high sensitivity navigation engine, it allows you to achieves the industry’s highest levels of sensitivity, accuracy, and Time-to- First-Fix (TTFF) with lowest power consumption. And with embedded antenna in SMT type, it is very easy to

embed into customer’s application.
