Impact of GPS/Galileo Integration on Marine Navigation

S. Ryan and G. Lachapelle

Abstract:	Reliable and accurate positions are required for general marine navigation and specialized applications such as buoy tending. The GPS signals are often masked by obstructions, which results in degraded geometry and accuracy at best, and unavailable or unreliable positions at worst. Once Galileo is implemented by the European Union, the use of a combined GPS + Galileo receiver will result in an increase of twice the number of satellites available above the horizon. The availability and reliability improvements attained, by augmenting GPS with Galileo and constraints under isotropic masking conditions and within a constricted waterway / urban canyon is illustrated through software simulations. These results clearly demonstrate the advantage of augmenting GPS with Galileo for marine navigation, especially under moderate to extreme masking conditions.
