SL3C GPS Module

GlobalTop FGPMMOSL3C is based on the latest MT3339 single chip solution. This new solution has low power consumption (20mA @ Tracking / 25mA @ Acquisition),and with support of up to 66 channels of satellite searching under -165dBm sensitivity, plus 10Hz maximum update rate for precise GPS signal processing under low receptive conditions.

FGPMMOSL3C is an ideal SMD solution for those who wish to incorporate GPS functions into their very small form factor device.
