JRC also makes a unit. It uses 2 antennae. Costs about $3,000. Read an
interesting article about these on one of the boating websites. The Furuno
unit has 3 antennae and can calculate additional information, for example,
roll period.

With 2 antennas it should be able to calculate pitch & roll. Our Vector Lite
only has 2 antennas (in the one package) and can calculate pitch or roll, (as
well as azimuth), depending on how you align it compared to the ship.
