==Spheres subsection of Geometric interpretation is misleading and= confusing==

The Spheres subsection of Geometric interpretation is misleading and confusing. '''This subsection should be completely removed.''' In this subsection, there is a statement that the solution is at the intersection of three sphere surfaces. This is completely misleading and is incompatible with the need for four or more spheres as concluded in the Langley paper and as we have tried to make clear in the Problem description section.<ref name="Langley"></ref> It is also stated in the paper, ,<ref name="Abel1">Abel, J.S. and Chaffee, J.W., "Existence and uniqueness of GPS solutions", ''IEEE Transactions on Aerospace and Electronic Systems'', vol:26, no:6, p:748-53, Sept. 1991.</ref>, that "GPS fixes are found as the point of intersection of four spheres centered on the satellites with radii given by the PRs corrected for user clock bias". This discussion of the solution being at the intersection of three sphere surfaces should be completely eliminated. [[User:RHB100|RHB100]] ([[User talk:RHB100|talk]]) 17:42, 20 July 2015 (UTC)

Does anyone have any objection to the deletion of this subsection? If so present your argument. Reading the Langley paper will help you understand why this subsection as it is currently written is confusing and misleading.<ref name="Langley"></ref> [[User:RHB100|RHB100]] ([[User talk:RHB100|talk]]) 01:11, 21 July 2015 (UTC)

The Hyperboloids sub-section does not in any way enhance the understanding of GPS. The
