Abstract
In this paper we model the controlled Lagrangian
particle tracking (CLPT) error for marine vehicles moving in an
ocean flow field, with guidance from ocean models. We linearize
the error about the nominal modeled trajectory of the system
and derive an exact expression for the linearized error in the
case of constant modeled ocean flow. We show that this simple
error model can be used to estimate error in predicted positions
of autonomous vehicles, using data from a field deployment of
autonomous underwater gliders in Long Bay, SC, in winter
2012.
