Hi Vanpham

It is quite likely that the orientation of GPS satellites will change during the day, the satellites are continuously moving and different ones are in use at different times of the day, also, their orbits are not perfectly synchronised and so their relative positions will also change during the day. With this in mind, it is quite possible the relative position of the satellites combined with the location of the unit on the boat and other equipment installed close to the AXIOM may have interfered with the Unit's internal GPS and prevented operation of the GPS.
