Block 3 has low accuracy GPS data (1.0 m), that is worse 
than accuracy of GCPs. It influenced the resulting accuracy. 
As shown in the table, computation speed is very high that 
gives the possibility of real-time quality control during 
measurement. 
10. Conclusion 
The real-time triangulation technology has been tested on 
many geodetic enterprises in Russia and Ukraine. In practical 
production became evident that block's RMS error does not 
exceed pixel size of block images. Maximum error is usually 
less than two pixels. 
Developed technology eliminates the most time consuming 
process of physical marking of tie points and also removes 
the accuracy loss connected with such marking. 
Real-time technology combining measurements, control and 
adjustment in single process produces reliable and error-free 
adjustment results for big and complicated blocks.
