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, --lou =============================================================== Louis H.
