Motorola GPS Products M12 Oncore User’s Guide Supplement Revision 1.0 01/25/00 SELF-TEST MESSAGE (12 CHANNEL) The GPS receiver user has the ability to perform an extensive self-test. The tests that are accomplished during the commanded self-test are as follows: • Antenna connection • RTC communication and time • Temperature sensor • RAM • FLASH ROM • Correlator IC The output of the self-test command is a 24-bit field, where each bit of the field represents Pass/Fail condition for each parameter tested. When the self-test is initiated, the next output message may not be the response. The self-test may take up to ten seconds to execute. Once the self-test is complete, the acquisition process starts all over as if the receiver were first powered on. The date, time, position, almanac and ephemeris information is all retained. 90
