The invention discloses a satellite navigation chip, a test method thereof and a receiver, and the test method comprises the following steps: a test device sends a radio frequency receiving test command containing a current test frequency point to the satellite navigation chip through a contacted instruction pin, and sends the radio frequency receiving test command containing the current test frequency point to the satellite navigation chip through a contacted radio frequency receiving pin; sending a test radio frequency signal under the current test frequency point to the satellite navigation chip; the central processing unit receives a test command according to the radio frequency and analyzes the test command to obtain the current test frequency point; the central processing unit configures parameters of the radio frequency receiving channel at the current test frequency point, controls the radio frequency receiving channel to convert the test radio frequency signal into intermediate frequency data, and ou
