Final Correlator Notes B o n n C o r r e l a t o r [ Geodetic Institute of University of Bonn ] IVS-R1194 (#1905) STATIONS -------- GILCREEK (Gc-A) > Ok. MATERA (Ma-I) > Low amplitude in channel "S4" (2312 MHz) causes about 29 % G-codes -> removed from fringe fitting. The remaining G-codes are caused due to low amplitude in channels "S1", "S2" or "S5". SVETLOE (Sv-S) > Six scans missed due to antenna problems. Manual phasecal in S-band and X-band. TIGO (Tc-O) > Last three or four X-band channels show always lower amplitude than the remaining X-band channels. That causes about 21 % H-codes or G-codes. Partly bad phasecal. Manual phasecal in S-band and X-band. TSUKUBA (Ts-U) > Ok. WETTZELL (Wz-V) > Lower sideband of first X-band channel (X1L) shows distorted bandpass shape due to a big unbalance between positive and negative bytes (more positive bytes than negative bytes).
