Abstract: This article discusses an algorithm for optimal spatiotemporal processing of navigation parameters in the presence of interference. The problem of estimating radio navigation parameters in GNSS receivers equipped with an antenna array is addressed. An optimal adaptive algorithm for determining navigation parameters using an antenna array based on GNSS signals in an unknown interference environment is synthesized. The main approaches to improving the computational efficiency of adaptive spatial-temporal processing algorithms in GNSS receivers are presented. It is shown that recursive updating of the R matrix using the QR factorization based on Givens rotations significantly improves computational efficiency. Examples of applying the CORDIC algorithm to recursive estimation of the R matrix and antenna array weights are given
