Patent number: 10816358Abstract: A test system for testing the positioning functionality of a device under test (DUT) is provided. The test system includes a high precision global navigation satellite system (GNSS) simulator configured to simulate real-time kinematic (RTK) signals. The test system further includes a sensor simulator configured to simulate ideal sensor signals, and a sensor error model unit. The sensor error model unit is further configured to simulate sensor errors based on a real sensor datasheet. The simulated ideal sensor signals are combined with the simulated sensor errors to form real simulation signals.Type: GrantFiled: July 10, 2018Date of Patent: October 27, 2020Assignee: Rohde & Schwarz GmbH & Co.
