How Can Curiosity Determine Her Own Position?

  A position line can be determined by a known point and its direction instead of using two points. One can use a variation of the previous method for finding Curiosity's position if the bearings of two known objects can be determined. One replaces Δ1 and Δ2 with unit vectors representing their directions and Δ3 is again the difference between the two positions. The calculation proceeds as follows using two of the known positions from the last blog and their calculated bearings from the determined position.
