Scheduling

  • With VieVS Satellite scheduling tool, by A. Hellerschmied
    • quasar block scheduled automatically
    • APOD scans manually scheduled
  • Schedule summary: 317b_sum_bearb.txt
  • Block of 5 strong quasars were observed before and after the APOD scans
    • Min scan duration set to 30 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

Observation

  • Observers: Jamie, Lucia, Andreas
  • Comments: ke overhead track, couldn't keep up at high elevations. Yg looked good, appeared to be stable throughout. Hb didn't look too good, weak and unstable at s-band, even at low elevation (very low elevation at Hb, slightly over 5 deg cut-off elevation).

Tracking

  • 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

Data and 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, TLEs
    • predicted WGS84 state vectors (1 sec interval, by J. Sun)
    • predicted AzEl posititons (1 sec interval, by J. Sun)
  • Results:
