GNSS programming with arduino

In GNSS processor in order to make some configuration how can we program it with arduino. I m using UBLOX receiver and it automatically converts gps to glonass. I have switched the glonass off but i am implementing my own algorithm on receiver with arduino on it. Can any body help in this regard...
