Abstract
A GNSS receiver having test signal based failure detection, comprises: a signal generator configured to generate a test signal, the test signal having characteristics of a GNSS signal; one of more amplifiers configured to amplify the test signal; a signal chain configured to receive the amplified test signal at an input node of the signal chain and process the received test signal; and a signal processor configured to: monitor the test signal by: obtaining one or more output signals of the device at one or more output node; recovering the test signal from the one or more output signals, and determining whether one or more errors occurred based on parameters of the recovered test signal based on parameters of the recovered test signal; identify a device failure based on the determined one or more errors; and generate notifications relating to the device failure.
