I presume you are referring to missing PPS pulses from a GPS receiver. In this case with a timing GPS receiver logging the timestamp associated with each PPS pulse should allow you to detect missing PPS pulses. The M12+T and M12M -T timing receivers can make this data available. Otherwise very coarse time stamping is more than sufficient to detect missing PPS pulses. Such time stamping can easily be done with a PC.
