描述 Description

SIM66M is a high performance and ?reliable GNSS module. It is a GNSS module integrated with GPS, GLONASS& Galileo* ?system in a LCC type with unicorecomm’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.

SIM66M provides simultaneous GPS, GLONASS, Galileo and QZSS open service L1 reception capability. With 46 tracking channels and 64 acquisition channels, SIM66M can acquire and track any mix of multiple satellite signals. Combining advanced AGNSS, SIM66M achieves the highest performance and fully meets the industrial standard.
