SIM33ELA 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 customer to achieve industry’s high level sensitivity, accuracy, and Time-to-First-Fix (TTFF) with lower power consumption. And with embedded antenna in LCC type, it is very easy for customer’s applications design.
SIM33ELA provides simultaneous GPS, GLONASS, Galileo and QZSS open service L1 reception capability. With 33 tracking channels and 99 acquisition channels, SIM33ELA can acquire and track any mix of multiple satellite signals. Combining advanced AGPS called EASY™ (Embedded Assist System) with proven AlwaysLocate™ technology, SIM33ELA achieves the highest performance and fully meets the industrial standard.
