Hellerschmied * quasar block scheduled automatically * APOD scans manually scheduled * Schedule summary: {{:wg7:apod:317a_sum_bearb.txt|}} * Sky plots: {{:wg7:apod:sky_317a_hb_0934-1015.pdf|}} {{:wg7:apod:sky_317a_ho_0934-1015.pdf|}} {{:wg7:apod:sky_317a_ke_0934-1015.pdf|}} * Block of 4 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**: Quasar recordings and tracking successful. No recordings during track for Ho and Hb, Ke started late; so no overlap. Ho signal looked good and stable (S-band). Hb (x-band) highly variable (about 1 sec period). Ke variable as well (in s-band) at high elevations. ==== 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 combined 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 (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) * For this session no delays could be obtained due to problems when observing the session. Basically there is no overlapping data of the two stations.
