• With VieVS Satellite scheduling tool, by A. Hellerschmied
  • quasar block scheduled automatically
  • APOD scans manually scheduled
• Schedule summary: 318b_sum.txt
• Block of 5 strong quasars were observed before the 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: Short hassles with the Ke elevation break not releasing, but solved before the track. All three tracks seem to be fine. It's becoming routine now. Good night, see you tomorrow morning.

• Satellite tracking based on direct AzEl input files
  • Azel values were calculated in VieVS based on predicted WGS84 state vectors (provided by J. Sun)
• Station equipment controlled by station dependent VEX files

• Files are available 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, TLEs
  • 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):
