This new GPS Lab website was created in December 2016. It updates and modernizes the original GPS Lab website that was created in the mid 1990s on Stanford's WAAS server—thus the GPS Lab website's original URL:

The original GPS Lab website was updated and maintained through ~2014. From 2014 through 2016, primarily  the Publications and Resources sections of the site were kept up to date.

In 2016, during  the process of migrating the contents of the original GPS Lab website to this new, content-managed and mobile-responsive GPS Lab website that your are vieing now, a considerable amount of old and out of date content was purposely omitted.

Thus, if you bookmarked a page or link on the old GPS Lab website and you've reached this page, the content you were seeking is not available on this web site.
