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: ------------------------------------------------------------------------------- COX0987N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09877.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ FIVE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 340 104 437389 10002 1.3 341 106 450378 10213 1.3 342 109 469867 10551 1.3 343 111 484036 10747 1.3 344 108 466760 10352 1.3 345 103 437517 10147 1.4 346 101 429860 10066 1.4 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103E104E106E109 110 111 113 116 117 118 120 122 ------------------------------------------------------------------------------- 340 10 6 6 20 30 15 17 26 5 5 7 4 341 9 5 4 21 29 8 12 17 6 5 9 3 342 6 2 5 7 15 10 10 17 5 4 6 5 343 13 5 3 10 16 12 14 15 4 2 3 6 344 5 4 3 13 16 12 8 18 5 3 3 4 345 11 4 6 9 22 9 12 14 5 5 7 5 346 11 5 5 16 29 29 22 30 6 4 6 6 ------------------------------------------------------------------------------- ALL 10 5 5 15 23 15 14 20 5 4 6 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: 23 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 5 PPP PP 28 59 85 BIPD 10094M001 7 PPPPPPP 4 10 18 BORG 12205M004 7 PPPPPPP 3 7 18 BRUG 13101M005 6 PPPPPP 5 16 40 DLRA 14208M002 7 PPPPPPP 3 9 14 GODZ 7 PPPPPPP 14 13 23 HERP 13212M009 7 PPPPPPP 11 13 32 IRKZ 7 PPPPPPP 5 7 10 KHAB 7 PPPPPPP 8 6 9 KR0G 10422M001 7 PPPPPPP 6 3 7 LDS1 13215M001 7 PPPPPPP 5 8 15 LRBA 10093M001 6 PPPPPP 2 7 5 METZ 10503M005 6 PPPPPP 5 4 4 MTKA 21741S002 7 PPPPPPP 9 7 7 NPLC 13234M001 7 PPPPPPP 53 46 78 OS0G 10402M004 7 PPPPPPP 4 5 6 REYZ 10202M003 5 PPPP P 6 5 15 STRR 50119M002 7 PPPPPPP 35 78 43 *) THU2 43001M002 7 PPPPPPP 6 8 10 TSKA 21730M003 5 PPPPP 10 6 10 VSLD 13502M008 6 P PPPPP 3 9 10 YARR 50107M006 7 PPPPPPP 36 81 32 *) ZIMZ 14001M005 7 PPPPPPP - - - FIXED ------------------------------------------------------------------------------- *) Very isolated sites -------------------------------------------------------------------------------
