Currently, in our country, we are completing the national elevation control network based on applying traditional technology and GNSS technology and using the Geoid model. Therefore, there is a requirement to solve the traditional geodetic network mixed correction problems and combine data obtained from GNSS technology, including information from the Continuous Reference Station (CORS). In the article, an algorithm to process a mixture of height network with elevation measurements and data from the CORS station was studied based on applying the theory of adjustment with the error of the original data and the recurrence adjustment. The proposed algorithm allows to calibrate the leveling network with the CORS point and can be divided into steps to analyze and evaluate the measurement quality of the network. The calculation results confirmed the reliability of the algorithm.
