Median Orbit Repeatability (see table below): 11.0 cm
According to the file nanu1997.mes obtained from the IGS CBIS, PRN05 was
unusable on day 307 for maintenance/repositioning. Data from this satellite
did not meet our initial convergence criteria on this nor the previous day
(306), and have been excluded from the analyses of both days.
A frequency shift was detected for GPS15 at approximately 15:35 UT on day 310.
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: PIE1 (not ALGO) used as reference clock day 306.
WARNING: NLIB (not ALGO) used as reference clock day 307.
WARNING: Data from PRN05 excluded on days 306 and 307 due to a maneuver.
WARNING: Data from CRO1, KOSG, WTZR excluded day 306.
WARNING: Data from CASA, CRO1, CSN1, HOLC, KELY, KSTU excluded day 307.
WARNING: Data from CASA, HOLC, KSTU, SANT excluded day 308.
WARNING: Data from CASA, KSTU excluded day 309.
WARNING: Data from KELY, MATE, SANT, XIAN excluded day 310.
WARNING: Data from HOLP excluded day 311.
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)
