1. Given are the following observations from point 1 to point 3:
From 1-2
Distance=423.45
Std. Dev.=0.04+4 ppm
Azimuth=120.2345
Std. Dev=10"
From 2-3
Distance=725.54
Std. Dev=0.04+4 ppm
Azimuth=245.5634
Std. Dev=10"
The variance covariance matrix of point 1 is:
0.04, -0.03
-0.03, 0.06
Assuming all the distance and angle observations are uncorrelated, compute the variance covariance matrix for points 2 and 3.
2. In problem 1, find the standard deviation of the distance, and azimuth from point 2 to 3.
3. Given 3 sides (uncorrelated) find the variance covariance matrix.
a=250m +-.015m
b=420m +-.020m
c=325m +-.018m
4. A distance is measured with three different instruments as shown below:
110.267m, sigma=+-0.003m
110.279m, sigma=+-0.004m
110.280m, sigma=+-0.005m
Compute the mean and its standard deviation.
