This is an excellent opportunity to learn from the experts about this new approach to OPUS – the NGS’ Online Positioning User Service. For those not familiar with the program OPUS provides simplified access to high-accuracy National Spatial Reference System (NSRS) coordinates. Upload a GPS data file collected with a survey-grade GPS receiver and obtain an NSRS position via email.
OPUS requires minimal user input and uses software which computes coordinates for NGS’ Continuously Operating Reference Station (CORS) network. The resulting positions are accurate and consistent with other National Spatial Reference System users.
Workshop Outline
- Introduction
- Step 1: Creating a Project
- Step 2: Uploading Data To Your Project
- Step 3: Session Processing
- Step 4: Network Adjustment
- Open Discussion
- One-on-one

What Is OPUS-Projects?
- Web-based access to process multiple marks and multiple occupations
- Data uploading through OPUS
- Data processing using the PAGES software
- Visualization and management aids
- Least squares adjustment
Do We Really Need Another OPUS Flavor?
- The NGS and other groups have a history of projects with specifications that can’t be entirely supported by OPUS.
- Yes, again. As well as OPUS does, sacrificing simplicity for flexibility can improve results in many cases.
What’s In This Workshop?
- By attending this workshop, you should have enough information to successfully use OPUS-Projects for your own projects. Once the training is completed, you’ll be given an opportunity to register your email address thereby authorizing you to create and process new OPUS-Projects.
- A project containing a training data set will be assigned to you. You’ll have an opportunity to work along with the presentations. In addition, time is allotted for you to explore your project individually.
