Static: OPUS determines your position with a differential GPS static solution, using hours of data.

This process is repeated 4x from other CORS.

OPUS-projects: first, run OPUS to harvest all project data

OPUS automatically forms sessions from simultaneously observed marks, enabling multi-baseline processing and adjustment of redundant observations.

What’s all that really mean for me?OPUS solutions = pretty good, but each treated as

independent and assumes “perfect” CORS.Sessions = simultaneously-observed marks processed

together in sessions increases consistency. Adjustments = interlinking sessions through network

adjustments increases accuracy.

Limitations?• Internet is required.

• Training is required for project managers.

• OPUS Static data restrictions apply.Dual-frequency static, 2 - 48 hours duration

• Project size.1 – 100 marks per session< a few hundred data files total

OPUS Projects TrainingBecause of its increased complexity, training is required to be an OPUS Projects manager. These workshops are usually two day in length and small so that there is ample time forone-on-one interaction with the instructor.

Check the NGS training center schedule for upcoming workshops run by NGS.
