  • Methods for modeling multipath reflections of GNSS signals using a test installation and apparatuses for implementing test methods
    Patent number: 10488524
    Abstract: A test installation for simulating multiple reflections of GNSS signals, the installation including a bottom screen that is reflective in the radio frequency spectrum; a top screen above the bottom screen, wherein the top screen is partly transparent in a radio frequency spectrum, and wherein the top screen is substantially dome-shaped and has a height of 1 to 3 meters; and a GNSS antenna between the top screen and the bottom screen; wherein the test installation is configured to measure the GNSS signals received by the antenna and to simulate the multipath reflections.
    Type: Grant
