【正文】 wave sources and even positioning algorithms can lead to nonacceptable solutions. These and other potential causes of accidental measurement errors must be taken under control to assure proper levels of accuracy. With the aim of protecting the system, MScMS implements a series of statistical tests for online diagnostics. Three of them are analyzed in the following sections: “energy modelbased diagnostics”。 “sensor physical diagnostics”. 5. Conclusion MScMSis an innovative wireless measuring systemplementar to CMMs. A prototype of this system has been developed at the industrial metrology and quality engineering laboratory of DISPEA Politeico di Torino. It is portable, not too much expensive, and suitable for largescale metrology (uneasy on conventional CMMs). Some innovative aspects of the system concern its online diagnostics tools. When dealing with measurement systems, the importance of a good diagnostics of produced measures is crucial for applications in which errors can lead to serious consequences. The diagnostics tools described in this paper, all based on the concept of “reliability of a measurement”, enable MScMS user to reject measurements which do not satisfy a series of statistical acceptance tests with a given confidence coefficient. For eachmeasurement, if all these tests are satisfied at once, the measured result is considered acceptable. Otherwise, the measurement is rejected. After rejection, the operator is asked to redo the measurement, changing the orientation/positioning of the probe or, if it is necessary, beacons arrangement in the system work. In same cases, the system might force to repeat a measurement too many times, causing an excessive extension of the measurement duration. This problem can be overe by changing the configuration of the constellation. Futurework, aswell as improving the power of the existing tools, will be aimed to enrich MScMS control system by implementing additional tools able to steer the operator during measurement. For example, suggesting the position of the probe in the measuring volume, or proposing possible extensions of the work of beacons, or automatically filtering and/or correcting corrupted measurements.
