all at the Jet Propulsion Laboratory, California Institute of Technology, 
Pasadena, CA  91109. (We welcome Mike Watkins, new Supervisor of JPL's
Satellite Geodesy and Geodynamics Systems Group, to the analysis team.)

According to the file gpsn1.txt obtained from tycho.usno.navy.mil, PRN22/GPS22
was scheduled unusable for up to 17 hours beginning at 18:35 on day 040 (Feb 9)
for repositioning.  We have excluded this satellite from the analyses of this
day and the following day as well.

Anti-spoofing has been in effect since day 031 (Jan 31).  All analyses were
done using our current A-S strategy; see jpl07347.sum for details.

WARNING: Due to the maneuver of PRN22/GPS22, data from this satellite have been          excluded  on days 040 and 041 (Feb 9, 10).
