REMARKS:  Starting with day 155 we are using a sligthly different
          estimation strategy. We are now estimation small velocity changes
          for all satellites twice per day, at 00:00 and 12:00 hours, in the
          along-track and radial directions. This means that for the 3-day 
          arcs 5 velocity changes are estimated for each satellite. Up to now we
          were only estimating velocity changes for the satellite in or near
          their eclipse period.
          Also starting this week we will be submitting so called SINEX files
          containing our coordinate solution based on the observations of
          this week.

REMARKS:  Day 158: Manoeuvre of Satellite PRN 22 ( 7-JUN-1995)
                   Satellite PRN 22 not included in the precise orbit file
