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.
