FIELD: physics.
SUBSTANCE: receiver for global navigation satellite system signal users has an antenna assembly consisting of two antennae, whose inputs are first and second data inputs of the receiver, and first - second analogue channels, two automatic gain control units, additionally comprising first and second adders, first and second switches, a built-in signal simulator with first and second simulation channels, each having series-connected amplifier and two mixers.
EFFECT: possibility of calibrating group delay time in the reception channel and processing reserved frequency of navigation signals of satellite systems, strict evaluation and accounting in software of user navigation equipment of the irregularity value of group delay time.
