Abstract

It is proposed to interpret the linear spline as an analog of the line of the position. In this case, the linear spline approximation is understood in two ways: the spline is associated with the line of the position and as the fragment of the restored navigational isoline at the same time. The author considered the construction of a gradient vector instead of a line of the position relative to its spline analogy, replacing the original isoline with a multi-link one. The new concept of a spline-gradient is introduced as an extended understanding of the classical gradient vector with the difference in the construction of the normal to the spline fragment approximating the isoline in a given neighborhood, and not to the conditional tangent or chord. The architecture fan of spline-gradients is estimated as a factor that determines the actual accuracy of the location of a marine mobile object. The author predicted that the proposed approach could be used as a mathematical support for the future automated navigation system with artificial intelligence within the framework of the concept of unmanned navigation in strategic accordance with the e-Navigation project.
