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. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
