GNSS (GPS and GLONASS)
SIM5360 merges GNSS (GPS/GLONASS) satellite and network information to provide a high-availability
solution that offers industry-leading accuracy and performance. This solution performs well, even in very
challenging environmental conditions where conventional GNSS receivers fail, and provides a platform to
enable wireless operators to address both location-based services and emergency mandates.
