• With VieVS Satellite scheduling tool, by A. Hellerschmied
  • quasar block scheduled automatically
  • APOD scans manually scheduled
• Schedule summary: 318c_sum.txt
• Block of 4 strong quasars was observed prior to APOD
  • Min scan duration set to 40 sec
  • Sub-netting deactivated
• See catalog files for full setup
• 1 sec time gap in VEX files between APOD scans
  • Continuous tracking and recording

• Observers: Jamie, Lucia
• Comments: Hb and Ke went fine. Unfortunately sattrack didn't want to run on the 26m =⇒ No data recorded at Ho

• Satellite tracking based on direct AzEl input files at Hb, Ke, Ho
• Azel values calculated in VieVS based on predicted APOD state vectors (pos. + vel., WGS84) provided by J. Sun
• Station equipment controlled with station dependent VEX files

• All control files used for the observations (VEX schedules, schedule summaries, orbit files, AzEl tracking files, etc.) are provided on the VieVS server (sorts@vievs.hg.tuwien.ac.at) at /home/sorts/apod/2016/
  • Azel tracking files for Ho, Hb, Ke
  • VEX file (station depended and combined)
  • VIE_SCHED files
    • used control + catalog files
  • predicted WGS84 state vectors (1 sec interval, by J. Sun)
  • predicted AzEl posititons (1 sec interval, by J. Sun)
  • final orbit solution (accuracy still less than 30 m according to J. Sun)
    • GCRF state vectors (pos. + vel.), 1 sec interval
    • WGS84 state vectors (pos. + vel.), 1 sec interval
• Results:
  • Plot showing fringe fitting results (residual multiband delays, delay rates, SNR, formal errors):
  • VSO observation files containing the multiband total delays calculated by HOPS/fourfit (remove the .txt file name extension to load the VSO files in VieVS): 318c.06_redclk-ion_free.vso.txt 318c.06_redclk-s.vso.txt 318c.06_redclk-x.vso.txt
