The problem of simulating movement of multiple gnss or regional navigational satellite system satellites across the sky within a test environment is solved by the technology disclosed using a test chamber with a plurality of zones bounded by azimuth and elevation limits, positioning at least one directional antenna in each zone, driving each antenna individually with a gnss simulator capable of producing multiple positioning signals for a plurality of satellite sources in a single zone, and coordinating among gnss simulators a simulated orbital movement of the satellite sources from one zone to an adjoining zone to produce changing angles of arrival for the positioning signals during a test. Both methods and systems implement this technology..
