Mean Orbit Repeatability (see table below): 26.6 cm
According to the file nanu1995.mes obtained from the IGS CBIS, PRN27 was
unusable on days 255 and 256 for maintenance/repositioning. Data from this
satellite did not meet our initial convergence criteria on these days, and
have been excluded from our analyses accordingly.
Also, PRN16 was poorly modeled on day 255. Although used in our processing
this day, we have elected to remove this satellite from the corresponding orbit
product (jpl08182.sp3).
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: Data from AOA1, CMP9, HBRK, KOKB, VCIO, WSMN excluded on day 253.
WARNING: Data from DAV1, HART, JPLM, KOKB, MAS1, NALL, TRAK excluded on day 254.
WARNING: Data from AOA1, DAV1, HART, MAS1, TRAK, WHI1 excluded on day 255.
WARNING: Data from PRN27 excluded on days 255 and 256.
WARNING: Data from AOA1, CHIL, CRFP, DAV1, FAIR, HART, KIRU, TRAK excluded on
day 256.
WARNING: Data from CHIL, DAV1, HART, KIRU, ONSA, YELL excluded on day 257.
WARNING: Data from AOA1, FARB, HART, KIRU, MATH, PERT, YELL, ZWEN excluded on
day 258.
WARNING: Data from AOA1, FARB, HART, KERG, NALL, PERT, YELL, ZWEN excluded on
day 259.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
