| Abstract: |
The GSFC VLBI group uses AIPS and Calc/Solve for geodetic and astrometric processing of VLBA correlated experiments, including the RDV, VCS1, VCS2, K/Q, and various antenna ties sessions. A VLBA vs. Mark4 correlator comparison shows group delay agreement averaging 12 psec RMS over baselines of 240 to 5000 km. Geodetic solutions for antenna axis offsets and fixed axis tilts are also presented. |
