<p>Dear IGS,</p>
<p>I am happy to announce the RINEX 4.00 format standard is finally
here, approved and adopted by the IGS in the Governing Board
meeting of 7 Dec 2021. You can find the format document in the
News announcement on the IGS website;</p>

<p>Additionally I have prepared the enclosed Open letter to the
community to highlight and explain a bit the changes from the
previous RINEX versions. Thanks for your patience and
understanding.<br>
</p>
