In this paper a new approach for GNSS carrier-phase data processing is presented. This approach is based on some properties of Amtoiguity Function Method. New algorithm ensures the condition of integer ambiguities without necessity of cornputing it explicitly. The condition of "integerity" of the ambiguities is ensured through inserting condition eouations in the functional model of adjustment problem. An appropriate, differentiable function for the condition equations is proposed. Some numerical problems connected with new approach were resolved using variable linear combinations of GNSS signals in cascade adjustment algorithm.
