Abstract
	Multi-antenna GNSS due to the high accuracy of relative coordinates determination (centimeter and millimeter accuracy), and relatively low cost, are widely used in various industries [1][2]. The main drawback of these systems is quite a long start period of each time of "capturing" satellite signals to estimate the fixed vector N of phase ambiguities. To eliminate this drawback, use a complexed multi-antenna system that continues calculating coordinates of base vector even if a signal loss occurs[3][4]. This article discusses the analysis of time that one needs to resolve the phase ambiguities, the estimation of error of N vector produced by complexed system and the criteria of fast resolution of fixed vector N. The analysis of time to resolve the phase ambiguities was produced. One needs three-five minutes to get the good Variance-Covariance matrix that provides to determine ideal integer vector N. LAMBDA method is used to calculate candidates for N vector[8][9]. The estimation of error of vector N was produced. The equation for calculating N vector without waiting the decorrelation of the elements is obtained. The criterion of resolving phase ambiguities was proposed. This criterion makes demands to the accuracy parameters of complexed multi-antenna system. When the criterion is met the time of getting the integer N values decreases from three minutes to one second.
