The covariant matrix of adjusted vector AU is equal to S = (C M, SR UR 12 ) (2.24)
Basing on the task described we can formulate new variants of aerotriangulation. For example when one part of the net
is constructed by the method of models and another part is constructed by the method of connections. Such
interpretation makes it possible to fulfill in a new way the densibleness of the net limited by the couple of the
photographs. Besides it is possible to construct models of locality and relief.

3. SOME PARTIAL PROBLEMS AND MODELS

eu Let us discuss some partial tasks that proceed from generalized model (2. 10) and which are of practical interest for
photogrammetry.
3.1.Measuring Y, was not made.
It leads the general statement to the task of joint adjustment of functions of measured quantities and the control data
with the mixed division of errors. Instead the system (2.10) we get

3.2. The task is analogous to the previous but with the condition that for the errors € , and y the law of the division
is normal (Gaussian).
