The Design of Special Purpose Horizontal Geodetic Control Networks.

摘要

The problem of the design of horizontal geodetic control networks and the choice of observations which will establish the network is examined from the standpoint of the final user specified positional accuracy and the required accuracies of user specified estimable quantities. A criterion variance covariance matrix is constructed solely from user requirements and predicted correlations from the propagated variance covariance matrix of possible establishing observations is used to choose those least correlated. An alternate approach is examined using the criterion variance covariance matrix and selected observations in a back solution for the observational accuracy required to recreate the positional parameter variance covariance matrix.
