• With VieVS Satellite scheduling tool, by A. Hellerschmied
  • quasar block scheduled automatically
  • APOD scans manually scheduled
• Schedule summary: 319a_sum.txt
• sky plots: sky_319a_hb_1000-1040.pdf sky_319a_ho_1000-1040.pdf sky_319a_ke_1000-1040.pdf sky_319a_yg_1000-1040.pdf
• Block of 4 strong quasars was observed before and after APOD scans
  • 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
• Min. 5 min time gap before after sat. scans to load antenna control files

• Observers: Jamie, Lucia
• Comments: 26m antenna was not available (no tracking). Couldn't observe the signal live on the SA (problems with internet connection)

• Satellite tracking based on direct AzEl input files
  • Azel values directly taken from tracking files provided by J. Sun
• Station equipment controlled by 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 all antennas (1 sec interval)
  • 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)
  • predicted GCRF state vectors (1 sec interval, by J. Sun)
• 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):
