Dear colleagues,

I have received a sample fileset (B & E files) created by the
Ashtech Datalogger 5.5 DOS software from an Ashtech GG24 OEM.
This also will accumulate a large L1 phase (absolute) value that
will overwhelm the RINEX format field width F14.3.

Modifications to the teqc translators for both the Z-18 and GG24 to
correct this will be forthcoming.

Best regards,
