WAYS OF MODELING MULTIPATH SIGNALS OF GLOBAL NAVIGATION SATELLITE SYSTEMS USING TEST BENCHES AND DEVICES FOR IMPLEMENTING TEST METHODS Russian patent published in 2017 - IPC H01Q9/12 

FIELD: physics.

SUBSTANCE: invention relates to the field of the test bench construction for carrying out radio measurements and experiments with signals of the Global Navigation Satellite Systems (GNSS). The stated test bench for simulating multiple signal reflection of the Global Navigation Satellite Systems (GNSS), includes an upper radio-translucent screen being predominantly dome-shaped; a lower radio-reflective screen; an upper translucent screen located above the lower reflective screen; and a GNSS antenna coupled to the receiver and located between the upper screen and the lower screen.

EFFECT: building test radio benches simulating the characteristics of the real obstacles, because of which satellite signals are repeatedly reflected and distorted.
