NGS "Bluebooking" process for GPS projects

The Adjust & Utilities program suite for GPS projects has been released to production. An update was required to allow non-shifted constrained coordinates to be written to the final B-file output.

This version of Adjust should be used to submit all GPS projects to NGS; projects submitted using previous versions will no longer be accepted after 30 days of this notice.

The previous release on July 13, 2015 was required so that new GPS project results are consistent with the NAD 83(2011/PA11/MA11) epoch 2010.00 realization. The main changes to the Bluebooking process are:

  • computation of horizontal and vertical project error scale factors;
  • use of variable weights on constrained stations;
  • determination of network and local accuracies.


  • This version of Adjust should be used to submit all GPS projects to NGS; projects submitted using previous versions will no longer be accepted.

    Please note:

    Earlier versions of Adjust prior to 6.4 write an incorrect value for the "up" component of local accuracies to the output Adjust summary file and bfile. Therefore versions of Adjust prior to 6.4 should not be used for submitting projects to NGS. The horizontal components of local accuracies and all components of network accuracies are correct in previous versions of Adjust.
