Network adjustment

  • 1.  Network adjustment

    Posted 2 days ago

    Hello all.

    I use TBC 5.70.

    In the network adjustment, during baseline processing, CORS-CORS vector are failed, but CORS-Rover vectors fixed, when I use IGS rapid SP3 and ERP.

    There are 4 CORS's 14 days data on 9-22th January 2026. But rovers' data are only 2-6 hours.

    But when I use 9-10th January IGS final SP3 and ERP, then CORS-CORS vectors are fixed.

    Has there any solution using IGS rapid SP3 and ERP files, and CORS-CORS would be fixed?

    Since your CORS are essentially known control points, I always disable baselines between them and use them as constraints

    HI Robert. Thank you for you feedback.

    CORS status are disabled. Yes I set up the CORS are used as constrains during baselines processing.

    Before, 1 years ago my TBC version 5.70 could process baselines constraints accepting Rapid Orbita parameters without any problem. But now only accepting Final Orbita parameters for CORS. 

    After a week all final orbita parameters would be available, then I can use them. But nearest days I need approximate coordinates using Rapid Orbita Parameters.
