CLOCK DRIFT PROFILE DETERMINATION IN NAVIGATION SYSTEM RECEIVERS

摘要

Navigation system receiver, and test circuits and methods for determining drift profile of a receiver clock in the navigation system receiver are disclosed. In an embodiment, the navigation system receiver (100) includes a clock source (130) configured to generate a receiver clock for the navigation system receiver and a test circuit (170). The test circuit is configured to facilitate determination of a drift profile associated with the receiver clock based on detection and tracking of a test signal received by the test circuit, where the test signal comprises at least one continuous wave (CW) signal.
