It has been designed to perform simple and rapid indoor dimensional measurements of largesize volumes (largescale metrology). It is made up of three basic parts: a “constellation” of wireless devices (Crickets), a mobile probe, and a PC to store and elaborate data. Crickets and mobile probe utilize ultrasound (US) transceivers in order to evaluate mutual distances. The system makes it possible to calculate the position – in terms of spatial coordinates – of the object points “touched” by the probe. Acquired data are then available for different types of elaboration (determination of distances, curves or surfaces of measured objects). In order to protect the system against causes of error such as, for example, US signal diffraction and reflection, external uncontrolled US sources (key jingling, neon blinking, etc.), or software nonacceptable solutions, MScMS implements some statistical tests for online diagnostics. Three of them are deeply analyzed in this paper: “energy modelbased diagnostics”, “distance modelbased diagnostics”, and “sensor physical diagnostics”. For each measurement, if all these tests are satisfied at once, the measured result may be considered acceptable with a specific confidence coefficient. Otherwise, the measurement is rejected. After a general description of the MScMS, the paper focuses on the description of these three online diagnostic tools. Some preliminary results achieved by the system prototype are also presented and discussed. 1. Introduction In many industrial fields (for example, automotive and aerospace) dimensional measurements of largesize objects should be easily and rapidly taken [1–5]. Nowadays, the problem can be handled using many metrological systems,
