SIMCom Wireless Solutions SIM33ELC GNSS module

SIM33ELC is a high-performance and reliable GNSS module. It is a standalone GNSS module with an embedded linear antenna on it. It is designed with MTK’s high sensitivity navigation engine, which allows customers to achieve the industry's high-level sensitivity, accuracy, and Time-to-First-Fix (TTFF) with lower power consumption. With the embedded antenna in LCC type, it is very easy for customer's application design.
