SIM33ELA 简介

SIMCom presents a high performance GPS module accompany with GNSS antenna - SIM33ELA. This is a standalone GNSS module embedded a linear antenna . 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.
