Abstract

This document presents instructions for the successful use of OPUS Projects (hereafter referred to as OP), the first version of OP specifically designed to streamline the process by which a user processes and submits campaign-style GNSS surveys for inclusion in the National Geodetic Survey’s authoritative database of survey control, known as the Integrated Database, or “IDB.” As a result of a successful NGS review and acceptance, the project files are archived by NGS and the authoritative, least squares-adjusted coordinates are published and made available to anyone with an internet connection via the NGS Datasheets. Throughout the document, this entire process is simply referred to as “submission to NGS.” This version of OPUS Projects (OP) has a very similar look and feel to previous versions, until the user specifies an official NGS-issued GNSS Project Tracking ID (provided through the Survey Project Proposal portal). The inclusion of this Tracking ID in OP unlocks new features of the software specifically for projects intended for submission to NGS. Note that although OP will support multiple GNSS constellations in the future, at the time of this manual’s publication, only GPS data files are supported.
