SIMCom presents a high performance GPS module accompany with GPS antenna-SIM39EAU. This is a standalone L1 frequency GPS 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.
