Theoretically in the simultaneous observation of the high-precision GPS network solution mode, the selection of the independent baseline vector can be arbitrary with the same adjustment. But in the real situation, the results varies in different selections for the model of baseline solution is imperfect[1].

Galileo is Europe’s contribution to the multi-GNSS to provide a highly accurate, guaranteed global positioning service under civilian control. Offering dual frequencies as standard, Galileo is expected to deliver extremely good realtime positioning accuracy. From users’ point of view, availability of Galileo’s signal would help in achieving a multi- GNSS environment for redundancy and system independence.

The International Maritime Organisation (IMO) is developing e-Navigation as the future approach to marine navigation in order to enhance maritime safety.
