Due to reported AS testing, various ground receivers were tracking in cross-
correlated mode beginning Jun 5 (day 156) at 00:01 UT. Our analysis of this day
includes all cross-correlated data, and have been processed using our AS
processing strategy (see jpl06867.sum).

Also, beginning Jun 1, we include data from FORT (Fortaleza, Brazil). The
following nominal coordinates were assumed, and the station location was
estimated (unconstrained) each day:

      X = 4985391.2017 m,    Y = 3955002.2179 m,    Z = -428426.3904 m

WARNING: No warnings for GPS week 699.
