SIM32EA中文资料GNSS数据手册SIMCom规格书

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.
