Abstract: Methods and apparatus for generating a test signal for a PNT configuration, and for testing a PNT configuration are disclosed. One such method comprises the steps of using one or more GNSS jamming signal detectors (100) to detect at least three different types of threat signal, each being an RF-based man-made GNSS jamming signal, and recording, to a database, information for the threat signals; receiving, from the database, information for at least one of the threat signals; generating a corresponding threat signal from the received information; and combining the corresponding threat signal with a PNT signal via a signal combiner to generate the test signal.

Abstract: The technology disclosed relates to testing hybrid positioning systems, including systems that rely on MEMS sensors. In particular, it relates to methods and devices for configuring and running tests of hybrid positioning systems.

Abstract: The technology disclosed relates to testing of connected vehicle systems. The connections involved are sometimes referred to as Car-2-Car (C2C), Vehicle-to-Vehicle (V2V), Car-2-Infrastructure (C2I), or Vehicle-to-Infrastructure (V2I). More generically, the connections are referred to as C2X and V2X. The technology disclosed provides an over the wire simulation of signals that a system will receive in operation, which allows testing of algorithms, breadboards, prototypes and complete systems. The system simulates the position of multiple on board units as the move with the vehicles that carry them. It attenuates signals between the OBUs and can attenuate signals among the OBUs and other test components, including roadside units and synthetic OBUs. The simulation is can be practiced as a method, a device, or computer readable medium that causes a device to practice the method or that, when combined with appropriate hardware, produces the device.
