MatLab functions set for manipulations with Navigation data. There are:
-- time/angle transformations (gNav),
-- coordinates datum’s and transformations (gNav),
-- Nod’s and Layback calculation (gNav),
-- Simple geometric tasks decision; for example, find cross-point for pipeline and survey line (gMap),
-- track-plots drawing with MatLab or AutoCAD scripts (gMap),
-- spikes manual removing (gMap).
The functions set used in Ge0MLib for geophysical equipment position calculation and track-plots drawing.
