Topcon Positioning Systems released the MG-A8 antenna for navigation and precise positioning in marine applications.

The antenna provides GNSS signal tracking while not being susceptible to signal jamming from other sources, such as Inmarsat communications.

The MG-A8 antenna can be used in DGPS mode for meter-level navigation purposes but can also be used for RTK centimeter-level positioning in areas where there is a network of reference stations available to support this level of precision.

With its RTK capabilities, the MG-A8 is a “preferred solution for applications such as dredging in inland river channels and waterways,” said Tom Morris, TPS senior product development manager.
