Some Thoughts on Testing the Data Quality Metric

Abstract

Over the last several years, Test and Training Ranges have been upgrading their telemetry receiving capabilities by integrating hardware that implement many of the link improvement techniques standardized within IRIG 106. One of these techniques is Data Quality Encapsulation (DQE) that includes the Data Quality Metric (DQM). The DQM assigns a quality metric to a set of data without a priori knowledge of the data. This metric can be highly useful if it accurately describes the quality of the data. This paper presents some initial thoughts on potential test methods that could aid in the determination of DQM accuracy. The approaches center on the use of differing transmission channels to corrupt the telemetry signal and then compare the estimated quality with the actual quality.
