Six initial conditions and nine radiation pressure para- meters per satellite were determined. No pseudo-stochastic pulses have been introduced up to now. - So far only receivers providing dual frequency GPS and GLONASS or dual fre- quency GLONASS measurements were included in the solution. - The daily orbit results stem from the middle day of a 5-day arc. - The satellite clock values included in the precise orbit files are broadcast clock values for the GLONASS satellites (no improvement done so far) and precise CODE estimates for the GPS satellites. - At present only the site ZIMZ (Zimmerwald, Switzerland) was constrained to its ITRF96 coordinates. ------------------------------------------------------------------------------- FILES SENT TO GLOBAL DATA CENTERS: ------------------------------------------------------------------------------- COX0992N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09927.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 10 103 440173 10174 1.4 11 103 423994 10384 1.4 12 101 392449 9960 1.4 13 101 392783 9842 1.4 14 101 393439 9842 1.4 15 101 388818 9885 1.4 16 99 381501 9691 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103 104 106 109 110 111 113 116 117E120E122E ------------------------------------------------------------------------------- 10 4 4 8 13 11 8 7 11 7 5 5 11 4 2 8 6 11 6 4 12 4 5 3 12 4 5 9 9 9 13 9 11 7 6 6 13 4 5 7 5 15 10 11 7 7 2 3 14 5 3 9 4 8 14 6 8 10 9 5 15 4 4 7 5 10 5 4 8 8 4 8 16 4 6 9 4 9 16 6 23 9 5 5 ------------------------------------------------------------------------------- ALL 4 4 8 7 11 11 7 12 8 5 5 ------------------------------------------------------------------------------- Remark: These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc. ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 24 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 7 PPPPPPP 43 133 322 BIPD 10094M001 6 PP PPPP 10 20 26 BORG 12205M004 5 PP PPP 6 5 18 BRUG 13101M005 7 PPPPPPP 78 18 79 HERP 13212M009 7 PPPPPPP 17 30 41 IRKZ 7 PPPPPPP 6 9 8 KHAB 7 PPPPPPP 8 7 8 KR0G 10422M001 6 PPPPPP 4 3 12 LDS1 13215M001 7 PPPPPPP 7 9 25 LINR 4 PPPP 25 35 70 LRBA 10093M001 6 P PPPPP 4 9 9 MDVZ 7 PPPPPPP 4 7 10 METZ 10503M005 7 PPPPPPP 3 5 13 MTKA 21741S002 2 P P 23 1 4 NPLC 13234M001 7 PPPPPPP 52 39 352 OS0G 10402M004 3 PP P 5 5 15 REUN 97401M003 7 PPPPPPP 8 19 15 REYZ 10202M003 7 PPPPPPP 4 5 10 STRR 50119M002 5 PPPPP 4 5 14 THU2 43001M002 6 PPPP PP 8 8 7 TSKA 21730M003 7 PPPPPPP 10 9 8 VSLD 13502M008 7 PPPPPPP 3 10 14 YARR 50107M006 7 PPPPPPP - - - FIXED ZIMZ 14001M005 7 PPPPPPP - - - FIXED -------------------------------------------------------------------------------
