First Patent to Verkotan, granted 14.12.2018

«Testing method and arrangement for GPS Positioning Measurements»

• The invention discloses a test method and arrangement for testing GNNS signals in a test chamber. The test chamber walls have transmitting antennas that transmit simulated satellite signals.
• Dynamic satellite movements are simulated to create a true satellite signal. All visible satellites are considered to create simulated GPS signals across the whole virtual sky. The device under the test is attached to a moving and rotating body phantom located in the center of the chamber.
• Radio channel properties are modeled according to real-life environments and programmed into a real-time channel emulator and then transmitted to the antennas in the chamber.
• Main application areas are sport watches, wearable health products, animal tracking and any device needing accurate positioning.
