For models with denied scale factor observation equations 
are as follows:

while for the models with denied rotation and scale factor 
the observation equations are of the following form: 
v 1 D dX X x" 
= . 9 - + "eh (4)

In the preceeding expressions (1) = (4) the following 
symbols have been used: 
i : point number; 
3 : model number; 
M Vy * : residuals of the observations; 
ax ,. d , dk , 
do’, (a9 b) : unknown orientation Parameters; 
xt, Y! ; approximate coordinates after first 
iteration of the classical block 
adjustment; 
x2, x? * approximate translation Parameters 
(expression (3)). 
At height adjustment the observation equations in the 
classical block adjustment are as follows:

For models with denied rotation parameters dd and dQ obser- 
vation equations are as follows:
