Abstract
A test set including a digital card tester section and a satellite simulator section is used to detect the reduced capabilities of an associated navigational satellite receiver and to isolate malfunctions therein. The digital card tester section is configured to generate digital signals (signatures) which are used to test and isolate faults in four digital system boards (cards) of the associated navigational satellite receiver. The satellite simulator section is configured to generate a facsimile of a navigational reference signal which is normally transmitted by an associated satellite system and received by the aforementioned associated navigational satellite receiver. The facsimile signal is used to test the receiver-processor section of the associated navigational satellite receiver.
