This toolbox can solve any of the 6 possible subproblems associated with an oblique spherical triangle, when only 3 of the 6 angles are known.The toolbox basically is an implementation of the set of tools developed in [Wertz, 2001], which aimed to fully automize the procedure and do away with the...

For purposes of these tools, a quaternion, q, is just a four element vector where q(1:3) is the "imaginary" or "vector" portion of the hypercomplex number, and q(4) is the "real" or "scalar" portion. Consequently, if q represents a rotation, then: q(1) = v1*sin(phi/2) q(2) = v2*sin(phi/2) q(3) =... Platforms: Matlab
