NGS updates "Bluebooking" process for GPS projects.

The "Bluebooking" adjustment process for GPS projects has been revised and is now available to the public for evaluation and use. An evaluation (beta) version of the adjustment software suite (including associated documentation) is available here . The beta version should be used to submit all GPS projects to NGS; projects submitted using the previous version will no longer be accepted. The evaluation period is expected to last one to two months, and during that time NGS welcomes your questions and comments.
