Gmm-u1 GPS Module
Gmm-u1
GlobalTop Technology's Gmm-u1 is the smallest and the most powerful GPS module total solution ever to utilize MediaTek's third generation MT3329 single chip GPS technology. At a dimension of 13x10 mm, Gmm-u1 is 15% smaller than its predecessor while preserving the ease of use and quality that stem from our SL lineup.
Gmm-u1 comes with -165 dBm ultra high sensitivity that can receive GPS signals in the harshest of condition, AGPS and DGPS support, multi-path detection and compensation, 10 Hz maximum update rate for high speed applications, plus the usual firmware customization service offered by GlobalTop to ensure your device obtain the maximum potential while using our GPS module.
