Subject: ANTEX v1.3 converter and software update


Dear BSW Users,

A new version of the ANTEX converter was already announced, see BSW
Mails 0216 and 0221 at http://www.bernese.unibe.ch/php/bswindex.php.

After a series of tests and improvements, a proved version of the
converter is now available together with a detailed readme file that
describes the converter and its options as well as the steps to be
followed to eventually switch to absolute antenna phase patterns:

A new BSW release, dated 27-Jun-2006, is available that includes

- PHCCNV ANTEX converter improvements and bug fixes,

- adequate handling of blank antenna radome code in RXOBV3 (automatic
  translation to NONE),
- helpful ADDNEQ2 features becoming relevant when considering antenna
  radome codes (or processing a mixture of old and new NEQ files),
- additional ADDNEQ2 improvements and bug fixes,
- corrected sign of the relativistic correction in the equation of
  satellite motion.

The last correction affects orbit estimation by changing the orbit scale
by +0.4 ppb. The effect on the terrestrial scale is negligible. For
usual applications, fitting of precise orbit information, the bug has no
effect and can be neglected for double-difference as well as precise
point positioning applications.

For a detailed list of bug fixes and improvements please be referred to

Please find the instructions on how to implement the new BSW update in
BSW Mail 0215 (http://www.aiub.unibe.ch/download/bswmail/bswmail.0215),
or at http://www.bernese.unibe.ch/support.html.

We hope that the new converter helps you to smoothly switch to absolute
antenna phase patterns. In case of problems or questions do not hesitate
to contact us (bernese@aiub.unibe.ch).

With best regards,

The BSW Team
