描述 Description

SIM32EA is a high performance and ?reliable GNSS module. It is a GNSS module integrated with GPS &GLONASS & Galileo & QZSSsystem in a LCC typewith AIROHA's high sensitivity navigation engine, which allows customer to achieveindustry's high level sensitivity, accuracy, and Time-to-First-Fix (TTFF) with lower power consumption.

SIM32EA provides simultaneous GPS, GLONASS , Galileo and QZSS open service L1 reception capability. With 47 GNSS receiver channels, SIM32EA can acquire and track any mix of multiple satellite signals. Combining advanced AGPS called EPOC? (Embedded Assist System) with proven AlwaysLocate? technology, SIM32EA achieves the higher performance and fully meets the industrial standard.
