Also compute the residuals of the observations and the standard deviations of the estimated three-dimensional coordinates of Point 5.

You will be computing the best estimate for the three-dimensional coordinates for Point 5 using four distances measured from Points 1, 2, 3 and 4 as per the tables and diagram given below.

Procedure i. Your first task will involve the generation of approximate three-dimensional coordinates for the unknown Point 5. ii. Using the Method of Least Squares, form the Jacobian matrix (J), misclosure (discrepancy) vector (k) and the weight matrix (P) for the linearized observation equations for horizontal distances. Compute the correction vector (dx) using the weighted Least Squares formulation. iv. Update your estimates for the three-dimensional coordinates for Point 5 and iterate the solution using Steps ii to iv until convergence is achieved. Depending on the quality of your initial estimates for the three-dimensional coordinates for Point 5, convergence will likely be achieved in two to three iterations You will be computing the best estimate for the three-dimensional coordinates for Point 5 using four distances measured from Points 1, 2, 3 and 4 as per the tables and diagram given below.
