A common INS performance metric used in military applications is CEP rate, generally calculated over typical INS mission times (a few hours, generally) and originally measured (before GNSS availability) during INS performance qualification trials aboard different military aircraft or surface vehicles on suitably instrumented test ranges. That can now be done using GNSS as the independent position solution for CEP rate determinations.
