QUESTION $3$:

The baselines of a $3$D network have been measured using GPS technique. The network and baselines are shown on the sketch. The baseline solutions have been accomplished by a GNSS processing software. Baseline components and their a priori variance$-$covariance information are given below. The units of the matrix elements are $m{m}^2.$ While the baselines are statistically independent from each other, there are correlations between baseline components.

The coordinates of station and $Z=4665836\mathrm{.}897m$ are taken as fixed coordinates.

By taking the baseline components as the observations adjust the GNSS network through the least squares estimation. Compute the adjusted coordinates and observations and their rms errors.
