[mathematical expression not reproducible] is pointing north, [mathematical expression not reproducible] is perpendicular to [mathematical expression not reproducible] and pointing nadir, and [mathematical expression not reproducible] is forming a clockwise

trihedron. Body axes are defined by subindex B.

Axes i is tangent to the Earth, j is orthogonal to i and runs against the gravity, and k is orthogonal to both i and j, setting up a right-handed

trihedron. The model is illustrated in Figure 2.

In is at this junction, between what is read and the reader, that the gravitational center is located for this method that you attempts respect the contributions of the different approaches that demarcate the

trihedron of critical knowledge (ibid, ibidem).

If we consider any orthogonal

trihedron as {[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]}, we can write their derivative formulas as follows:

[10] expressed a family of surfaces from a given spacelike or timelike asymptotic curve using the Frenet

trihedron frame of the curve in Minkowski 3-space [E.sup.3.sub.1].

where O is the center of mass of the Earth, the axis O[xi] running to the perigee, the axis O[zeta] pointing to the angular momentum, and the axis O[eta] making a direct

A

trihedron ([T.sub.0]; [e.sub.1], [e.sub.2], [e.sub.3]), with a proper origin [T.sub.0] ([x.sub.0],[y.sub.0],[z.sub.0]) ~ (1 : [x.sub.0] : [y.sub.0] : [z.sub.0]), is orthonormal in pseudo-Galilean sense iff the vectors [e.sub.1], [e.sub.2], [e.sub.3] have the following form: [e.sub.1] = (1, [y.sub.1], [z.sub.1]), [e.sub.2] = (0, [y.sub.2], [z.sub.2]), [e.sub.3] = (0, [epsilon][z.sub.2], [epsilon][y.sub.2]), with [y.sup.2.sub.2] = [z.sup.2.sub.2] = [delta], where each of [epsilon], [delta] is +1, or -1.

It can be stated that this domain of inter-relations forms a

trihedron of knowledge (savoir) that can be called modern episteme.
