The aim is to develop an adaptive hardware and software complex (AHC) that provides increased noise immunity of satellite radio navigation systems (SRNS) equipment Main results. The mathematical modelling of the adaptation algorithm and its synthesis were carried out, taking into account the contradiction of requirements to ensure its speed and stability, to take into account the significant influence of destabilising factors on the process of calculating the adaptation weights and the construction of the diagramming system.A prototype of the AASC was created, which provides for the development of adaptation algorithms and semi-natural studies.   Experimental 4-element antenna array
