The core Wave Glider platform consists of the float equipped with communications devices and a central control computer, the umbilical, and the Sub. The specifications below apply to the base Wave Glider platform. Individual Wave Glider models (METOC, METOC Plus, Gateway), and Configured-to-Order Wave Gliders can have different specifications.
