Global satellite navigation receivers are widely used in different technical applications and national economy that is caused of high accuracy of navigation definitions when are used. Especially high accuracy is reached when using phase measurement. It is known that using phase measurement there is existed phase ambiguity. To resolve this problem there are proposed different approaches that are differed by that or those approximations used for synthesis and difficulty of realization. Further investigation in this area with using of optimal filtering approaches to eliminate phase ambiguity is an actual task. In the article there is examined one of the such approaches that is based on introducing of additional variable. This method permits to divide tracking of envelope delay and phase delay with accurate estimation of number of phase ambiguity periods. The synthesis of optimal discreet tracking algorithm of signal delay with processing of envelope and phase and using observation grouping is fulfilled. There is analyzed an effectiveness of synthesized algorithm.
