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.
