Firefly 1

GlobalTop | Multi-GNSS Module
Firefly 1
Firefly 1 is build based on MT3333 Multi-GNSS engine capable of achieving the high level of sensitivity (-165dBm) and instant Time-to-First Fix (TTFF).
Firefly 1 is a dual system GNSS receiver which acquires and tracks GPS/Glonass systems concurrently to provide high sensitivity and positioning capability.
