The following files have been sent to the CDDIS:

jpl0722[0-6].sp3       GPS ephemerides for GPS week 722, sp3 format.
______________________________________________________________________________

Due to anti-spoofing, various receivers were tracking in cross-correlated mode
on days 312 and 313 (November 8 and 9).  Our A-S strategy was used for the
analyses of these two days only; see jpl07147.sum for details.

Tracking data from HOBA (Hobart, Tasmania) and KOUR (Kourou, Fr. Guiana) have
been deleted for the entire week of analysis (no data for KOUR available on
day 313). Inclusion of one or both of these sites has caused an excessive
number of outliers in our solutions.

WARNING: Data from HOBA and KOUR have been excluded the entire GPS week 722.
