Specifying Holdover Performance
• What happens when GNSS clocks lose lock? • What does holdover mean? • Why is it difficult to compare holdover claims between manufacturers? • Why do we specify holdover over a complete range of environmental parameters? • What makes us confident in our claims? We hold two patents (US 9 362 926 and US 9 979 406) for ‘High-Reliability Holdover Method and Topologies’ which offer several improvements to previous state of the art. read more »

What is Accuracy?
When manufacturers use accuracy values to define the performance of their products, consumers should have confidence that, in fact, the products do perform to the stated levels. However, that is not always the case. This paper takes a look at several misconceptions about "accuracy" - particularly within the measurement and control markets of the electric utility industry - and discusses various methodologies that can be adopted to justify claims and ratings. read more »
