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: ------------------------------------------------------------------------------- COX0985N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09857.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ THREE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 326 84 366586 8831 1.3 327 87 384764 9287 1.3 328 91 409405 9640 1.3 329 96 442879 10207 1.3 330 98 459766 10342 1.3 331 98 463821 10206 1.3 332 100 480333 10408 1.3 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103E104E106E109 110 111 113 115 116 117 118 120 122 ------------------------------------------------------------------------------- 326 6 4 6 6 13 7 5 18 12 7 5 5 3 327 7 4 3 6 23 9 6 5 5 6 4 6 3 328 5 5 5 11 12 4 4 4 6 6 2 5 5 329 3 4 3 4 19 5 5 4 4 4 4 3 4 330 7 4 7 5 16 4 3 5 4 5 6 4 4 331 7 4 9 7 24 6 7 5 3 3 6 4 5 332 7 6 8 7 12 7 5 6 6 3 10 4 5 ------------------------------------------------------------------------------- ALL 6 4 6 7 18 6 5 8 6 5 6 5 4 ------------------------------------------------------------------------------- Remark: These RMS values may be too optimistic, because we fit the middle days of 5-day arcs with a 7-day arc. The improvement made compared the previous week is mainly due to new sites that we could introduce. ------------------------------------------------------------------------------- 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 15 24 48 BIPD 10094M001 6 PPPP PP 6 12 14 BORG 12205M004 5 P PPPP 4 5 11 BRUG 13101M005 7 PPPPPPP 10 8 15 DLRA 14208M002 7 PPPPPPP 3 7 8 GODZ 7 PPPPPPP 3 4 7 HERP 13212M009 6 PPPPP 15 14 41 IRKZ 6 PPPPPP 6 2 12 KHAB 6 PP PPPP 12 7 8 KR0G 10422M001 7 PPPPPPP 3 4 6 LDS1 13215M001 7 PPPPPPP 4 11 23 LRBA 10093M001 7 PPPPPPP 1 6 2 METZ 10503M005 2 PP 2 1 5 MTKA 21741S002 2 PP 5 1 11 OS0G 10402M004 7 PPPPPPP 2 5 6 REYZ 10202M003 6 PPPPPP 3 3 4 SANG 41705M005 3 P P P 195 437 385 *) SL1X 40446S001 7 PPPPPPP 3 6 8 STRR 50119M002 5 PPPPP 55 67 65 *) THU2 43001M002 5 PPPPP 2 4 9 TSKA 21730M003 4 P PPP 8 10 1 VSLD 13502M008 6 PPPPPP 4 5 3 YARR 50107M006 5 PPPPP 53 47 76 *) ZIMZ 14001M005 7 PPPPPPP - - - FIXED ------------------------------------------------------------------------------- # Coordinate Estimates: 136 29 55 61 *) Very isolated sites -------------------------------------------------------------------------------
