Subsequent to IGS Mail 5401, further changes have been proposed for the
RINEX 3.00 format.  The clock RINEX format has been updated accordingly.
A summary of proposed changes is:

  a. "RINEX VERSION / TYPE" header changed to 3.00 and to add satellite
     system designator.
  b. "PGM / RUN BY / DATE" header date format elaborated.
  c. "SYS / # / OBS TYPES" header added.
  d. Added Galileo and Space-Based Augmentation System (SBAS) satellite
     designators in Section 5.
  e. "TIME SYSTEM ID" header added.
  f. The satellite antenna phase center offset information has been moved
     from a mandatory comment to the "SAT ANT PCO / PCV" header and now
     includes the associated phase center variation information also.
     It is expected that an external file will be referenced.
  g. "SYS / DCBS APPLIED" header added.
  h. Capability of handling inter-system timing biases and new intra-lab
     biases (possibly as new types of CR data record) are under
     consideration but not yet adopted.

Send any comments to me and Werner Gurtner (werner.gurtner at aiub.unibe.ch)
so that finalization can be completed within the next few weeks.

Thanks,
