The internal consistency tests and the comparison with SLR show better RMS values for this solution type compared to the results from 3-day arcs submitted in previous weeks. ------------------------------------------------------------------------------- PROCESSING STRATEGY: ------------------------------------------------------------------------------- - The analysis was done by fixing the GPS orbits and Earth rotation parameters to the CODE final GPS solution. - The orbital parameters for the GLONASS satellites were estimated using double difference phase observations (including double differences between GLONASS and GPS satellites). 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: ------------------------------------------------------------------------------- COX0983N.EPH GLONASS/GPS DAILY SATELLITE EPHEMERIDES, SP3 FORMAT (N=0..6) COX09837.SUM THIS TEXT FILE ------------------------------------------------------------------------------- ------------------------------------------------------ THREE DAY SOLUTION STATISTICS: ------------------------------------------------------ MIDDLE DAY FILES OBSERVATIONS PARAMETERS RMS (MM) ------------------------------------------------------ 312 71 314168 7237 1.4 313 72 292564 7034 1.3 314 75 288600 7051 1.3 315 79 288156 7185 1.3 316 83 308732 7709 1.3 317 81 311903 7646 1.2 318 78 308212 7493 1.2 ------------------------------------------------------ ------------------------------------------------------------------------------- ORBIT REPEATABILITY FROM A 7-DAY FIT THROUGH DAILY ORBIT SOLUTIONS (CM) ------------------------------------------------------------------------------- 103E104E106E109 110 111 113 115 116 117 118 120 122 ------------------------------------------------------------------------------- 312 33 39 37 56 64 92 56 87 88 19 26 22 23 313 26 27 40 45 54 71 42 66 65 21 21 18 20 314 26 31 32 49 68 61 45 60 53 19 23 19 20 315 35 30 42 49 64 46 50 55 50 20 23 22 24 316 37 34 38 44 56 70 51 73 79 22 24 19 24 317 30 26 32 24 63 66 48 63 81 18 21 18 21 318 50 40 45 42 67 89 57 81 83 23 30 24 29 ------------------------------------------------------------------------------- ALL 35 33 38 45 62 73 50 70 73 20 24 20 23 ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- WEEKLY COORDINATE COMPARISON OF 1-DAY (Z1) SOLUTIONS ------------------------------------------------------------------------------- TOTAL NUMBER OF STATIONS: 19 ------------------------------------------------------------------------------- WEEKDAY RESIDUAL RMS IN MM STATION #DAYS 0123456 N E U ------------------------------------------------------------------------------- 3SNA 49918S001 6 PPP PP 36 117 113 BIPD 10094M001 5 PPPPP 4 11 11 BORG 12205M004 6 PPPPPP 5 8 15 BRUG 13101M005 7 PPPPPPP 6 11 17 DLRA 14208M002 7 PPPPPPP 6 12 13 GODZ 5 PP PPP 8 11 8 HERP 13212M009 5 PPPPP 8 17 37 IRKZ 5 PPPP P 5 9 12 KHAB 7 PPPP P 7 7 10 KR0G 10422M001 7 PPPPPPP 3 5 5 LDS1 13215M001 7 PPPPPPP 5 8 14 LRBA 10093M001 6 P PPPPP 3 4 5 METZ 10503M005 5 PPPPP 2 5 3 MTKA 21741S002 3 PPP 6 12 2 OS0G 10402M004 6 PP PPPP 2 5 8 REYZ 10202M003 1 P - - - SL1X 40446S001 7 PPPPPPP 7 7 10 VSLD 13502M008 7 PPPPP P 7 14 29 ZIMZ 14001M005 7 PPPPPPP 1 1 1 -------------------------------------------------------------------------------
