What are the IGS products?
A table of products with their update schedules, formats, accuracies, access details, etc. is available at http://igscb.jpl.nasa.gov/components/prods.html” From the Charter for IGS Analysis Centers and Associate Analysis Centers”:”IGS products are formed from a combination of independent results submitted by the IGS Analysis Centers. To the extent that the effect of data and mismodeling among different Analysis Centers are independent, properly weighted combinations of results can be superior. In this way, the IGS products benefit in precision, accuracy, stability, reliability, and robustness compared to the results of any individual AC.” The IGS Analysis Center Coordinator’s page is also an informative source about recent performance of the classic IGS products.
