Overview

GlobalTop Ivory 1 (Gmm-u1315) GPS receive module is built based on the latest MT3339 single chip solution. Gmm-u1315 module provides maximum sensitivity while maintaining low system power (20mA @ Tracking / 25mA @ Acquisition). It supports of up to 66 channels of satellite searching under -165dBm sensitivity for precise GPS signal processing under low receptive conditions.

Ivory 1 is an ideal SMD solution for those who wish to incorporate GPS functions into their very small form factor device.
