Ublox NEO-M9N cold start - Custom breakout board

Testing my custom Ublox NEO-M9N breakout board with u-center software. The blue led starts to blink as soon as the GPS has a valid fix. As you can see from the Satellite Position View in u-center, the antenna doesn&have a full view of the sky because it was positioned on the window sill of the house. Despite that the cold start time is good. Antenna: The details of the board, Schematic, Gerber and Bill of Materials files are available here: Test of the board:
